If I paid a non-refundable hundred-plus dollars, drove so many hours to the track, and it's safe go out and have some fun, I'm riding. I'm never turning a wheel on a wet Midohio again, but I've enjoyed wet Beaver at both 75F/heavy rain and 37F/damp. If the day started dry and then turns wet it really sucks, since you were already at that pace, but sometimes those days that start wet and then dry out just make it that much sweeter...
