Golfers in the over-50 set with their huge colorful golf bags began arriving Monday afternoon at the Jeremy Ranch Golf Club ready to tackle the Showdown Classic golf tournament, which will be played this week.

For some like Miller Barber it's a chance to get reacquainted with an old friend. Barber has played in every PGA senior tournament at Jeremy Ranch since the initial event in 1982 and the old course has been good to him. He's been the most successful of anyone with a win last year, in 1985 with Ben Crenshaw when it was a best-ball event and a second-place finish in 1982.For others, like Al Geiberger, Tommy Aaron and Homero Blancas, PGA Tour rookies, it is their first opportunity to see the 6,947-yard Jeremy layout, which sits in the mountains east of Salt Lake and north of Park City.

A full week of activites are on tap with the 54-hole tournament proper not getting under way until Friday, continuing through Sunday.

Tuesday, like Monday, was a practice round for most of the golfers. Tuesday night the draw party will be held, where amateurs will find out their pro partners in the pro-ams. The pro-ams, featuring a pro with four amateurs start Wednesday and continue Thursday. Wednesday at 3:30 p.m. a clinic will be held out on the practice range with trick-shot artist Bob Brue, Bobby Nichols and Bruce Crampton.

Several of the top players from the Senior Tour will be on hand this week, including defending champ Barber, Crampton the winner of last week's Northwest Classic in Washington, former champion Bobby Nichols, Geiberger, the Tour's No. 6 leading

money-winner and Orville Moody, the No. 2 money-winner on the Senior circuit this year. Other familiar names playing include Dale Douglass, Gene Littler, Charles Coody and Peter Thomson.

A few local senior golfers such as Lanny Nielsen, Don Johnson and Dick Peacock, have been given sponsor's exemptions in the 72-man field.

Among the missing are Gary Player, Chi Chi Rodriguez, Billy Casper, Don January, Arnold Palmer, and Bob Charles, the Senior Tour leading money winner.

Tee-times will begin at around 8:30 a.m. each day. Tickets can be purchased at Smiths-Tix or at Jeremy Ranch.
