Through the years, the competitors at the Potomac Valley Athletics Council outdoor track meet have resembled performers at a successful Indian rain dance.

Today's edition at Byrd Stadium, however, figures to benefit from someone else's weather problems. Last week's IC4A meet at Princeton was conducted under such miserable circumstances that few athletes who had hoped to qualify for the NCAA championships in Provo, Utah, June 2-5 were able to meet the standards.

Accordingly, athletes from up and down the East Coast, including Villanova, Penn State, Pittsburgh, Richmond and Virginia Tech, as well as Georgetown and Maryland, are coming here for a last-chance attempt at NCAA berths.

As an added benefit, two of those schools will bring along assistant coaches whose presence will lend unaccustomed glitter to the program. They are Don Paige of Villanova, the national indoor 1,000-yard champion, and Mike Shine of Penn State, silver medalist in the 400-meter hurdles in the 1976 Olympics.

Paige is entered in the meet's spotlighted event, the 800 meters, scheduled for a 2:10 p.m. start. Among his opponents will be Mike England and John Hunter of Villanova, Brian McNelis of Georgetown and Julian Spooner of Richmond.

Shine's intermediate-hurdles opposition will include Fred Sowerby, Tim Hanlon, Craig Morris and Chris Person.

The top women's event will be the 400 meters, matching Roberta Belle and Michele Collins. Maryland's Marita Walton, the national indoor shot put champion, will compete in her specialty as well as the discus.

There will be no post entries, the list having closed a week ago. Admission is free, with action commencing at 9 a.m. and finishing at about 4:15.
