Where I live (been 100 degrees for the last 6 days), the roads melt and get sticky. Of course, if it's a concrete track....that's a different story???
Back in the 60s I attended the Summer Nationals in Poteet, Texas...about 100 miles from here. It was hotter than hell (high 90s) but it was a blast!!!!!!!!
I'm in north Texas and I went to Xtreme Raceway Park last night. It wasn't as brutal as I thought it would be, and the track is all concrete so people were hooking just fine.
