Haven't heard whether they've rained out for today, but they had 27 late models and 44 mods in prelims Friday night. B-mains and features are today (Saturday). $5,000 to win late models, $3,000 (I think) in modifieds. I saw a few St. Louis-area guys raced Friday, including Brian Wolfmeier and Mike Hammerle.
If they rain out, races will be made up Sunday afternoon. If that rains out, it's on for next Saturday, Nov. 1. Their web site is maldenspeedway.com with phone numbers and more info.
