I, too tend to believe that the cost of racing, at least in the "upper" classes, has been priced out of a "weekly" activity, for many of the owners/drivers. And as much as I'd like to see Spencer Speedway continue to operate, they're STILL, after all these years, fighting with 3-4 "neighbors", who are trying to get the track shut down for good. Sad situation....
Furthermore, while somewhat off the topic, the NASCAR Monster Cup series ran a race at Indy this past weekend. Even though the race ended fairly early, the Rochester daily newspaper had nothing but the finishing order, listed on the "box score" page. No other mention of the race. They did, however, have 3-4 full pages of drivel on the Buffalo Bills game, as those guys actually won a game.
I think we motorsports fans are facing an even tougher, uphill battle.
