Old Dominion Speedway ends its season Saturday night with the 25th Blue-Gray 150-lap (56.25 miles) race for late-model and limited-sportsman class sedans. The $5,000 purse has attracted Ray Hendrick, winner of more than 800 stock car features in his 20-year career; Sonny Hutchins, and Tommy Ellis.

The current point leader at the Manassas oval, Reds Kagle, has entered to protect his slim 19-point margin over Bobby Ballentine. Jack Bland, winner of the Sheets "100" last week, is another local hopeful. Racing begins at 8 p.m. with events for street stock sedans also on the program.

Three days of drag racing begin Saturday night at 8 p.m. at Maryland International in Budds Creek, Md., with a regular match-race program. Sunday is the annual team championship meet with a $4,000 purse. Three-car teams comprising a single entry from the pro, heavy and street eliminator classes compete, with points going to winners and starters in each round. Monday afternoon's show is another match-race tourney for these classes and the super pros. The afternoon racing begins at 2 p.m. each day.

Dorsey (Md.) Speedway has two more Saturday night shows this year. A double-point race of 35 laps over the quarter-mile dirt oval for late-model sedans is this week's feature. Five figure eight races will also be run.

Potomac Speedway at Budds Creek may continue its Saturday programs into October. This week's show is for the regular three classes of sedans on the three-eighths-mile dirt track.
