Currently racing in the rain and the racing is awesome. Way too much power, way to small tires, too small brakes. Watching the cars get sideways when the drivers roll onto the throttle and the front ends wiggle under braking is incredible to watch.
For those that don't watch road racing regularly, Mid-Ohio is one of the most treacherous tracks in the wet. The surface is worn and doesn't give the tires anything to grab onto. Couple that to the patches in the corners which are even slicker it becomes a challenge. Even if you stick to the outside of the corner for traction you have to come across the patch at some point in most of the corners.
