Sedalia's recorded ground centres on Castle Pines Village, a gated community platted from 1981 around Castle Pines Golf Club, once neighboured by The International, a PGA Tour event built for its thin mountain air that ran from 1986 until the Tour cancelled it outright in 2007.

The short answer

Castle Pines Village, Colorado, a gated community platted around Castle Pines Golf Club from 1981, stood roughly half a mile from The International, a PGA Tour event played there from 1986 to 2006 under a unique Modified Stableford scoring system designed for the course's high, thin air before the Tour canceled it outright in 2007.

1986 to 2006

A golf tournament scored points instead of strokes

For twenty-one years, professional golfers came to a course cut into a Colorado tableland. They played a format used at no other stop on the PGA Tour. The International (golf) sat at the Castle Pines Golf Club, roughly 970 yards from this point, at an elevation of about 6,300 feet. Ordinary stroke play, where every shot counts against par, breaks down at that altitude. Thin air lets a ball fly farther and bounce harder, so scores swing wildly and low numbers stop meaning much.

The tournament's answer was the Modified Stableford system. Instead of counting strokes, it awarded points. An albatross earned eight points. An eagle earned five. A birdie earned two. Par earned zero. Anything worse cost points. The system rewarded a player willing to gamble for a low score on a hole. A bogey cost little. A double or triple cost plenty. It was designed to make aggressive, high-elevation golf make sense on a scorecard.

Jack A. Vickers built the course and founded the tournament that ran on it. He hired Nicklaus to design the club and opened it in 1981, five years before the first International teed off. The format he backed stayed unique on Tour for two decades, tried again only once more, at Reno in 2012, after this one was gone.

It was one of only two PGA Tour events never decided by ordinary stroke play.
2007

The Tour canceled The International outright

In 2007, Tour officials agreed to move The International to a new slot on the calendar. The tournament would shift to the first weekend of July, wedged between the U. S. Open and the British Open. The hope was to draw bigger names, Tiger Woods among them, away from a date the week before the year's final major.

The change came too late to matter. On February 8, 2007, the PGA Tour announced it was canceling The International outright. Its replacement was the AT&T National, hosted by the Tiger Woods Foundation, and played near sea level under standard stroke play. Vickers and the club's members had reportedly soured on the direction the Tour was taking, even with the new date secured. Twenty-one years of golf built around the mountain's thin air ended with a tournament moved to sea level, scored the ordinary way.

mid-to-late 1800s

Outlaws waited along a Denver stagecoach road

Long before Vickers laid out fairways on this tableland, the ground served rougher traffic. Stagecoaches ran between Denver and Colorado Springs across this high country. Outlaws knew the terrain well. They waited along the road for travelers. They picked spots where the land gave them cover and escape routes. The same elevation and folded ground that later made golfers rethink their scores once gave robbers their advantage. Nobody tamed this tableland easily, whether they came with a stagecoach or a set of clubs.

2003

A utility trench on Hidden Pond Road hit a mystery

Utility crews dug trenches for Hidden Pond Road in 2003. They hit something that stopped the work. What came out of the ground drew attention. People compared the find to a detective story. Nobody quite explained the ending. The items surfaced within a quarter mile of the golf club Vickers had built two decades earlier. They were on the same stretch of high ground. The tableland has a habit of giving up things nobody expected.

The land kept its secrets. The community built on top of it changed its name instead.
1981 to 2018

A gated village renamed itself after forty years

Castle Pines Village, Colorado went up in 1981. It was a gated community wrapped around Vickers's new golf club. It sat roughly half a mile from where The International would later be played. It grew for decades as a private enclave. It kept its residents inside and everyone else out. In September 2018, the Castle Pines Homes Association renamed it The Village at Castle Pines. The move separated the community from the newer city of Castle Pines taking shape nearby. A gated development that had spent almost forty years under one name decided its identity needed adjusting. The world around it changed.

The fairways Vickers built for thin air now sit quiet, the tournament gone, the tableland still standing.
