The hassle factor makes a big difference to me. My trailer is big enough to carry everything, so I don't have to load and unload the car each time. Most of the tools in the trailer are duplicates, so I can just leave the trailer loaded except for the tires.
There isn't a road course close enough to me to make open tracking an option, and National/Divisional/ProSolo autocrosses are also too far away and/or too big of a time commitment. Sooner or later, I'm going to have to quit this nonsense altogether.
For now, local autocross is what I
can do, so that's what I do. I can even enjoy the 1st gear courses, as long as I get to use WOT a lot. First is a lot of fun with an LS1 (IMG:
