Reasons I didn't enter last year and haven't this year:
1) Cost of entry fee. I would rather spend the money on improvements to my vehicles.
2) Neither of my vehicles fit well into any of the categories to be even close to competitive.
3) I just like to wheel. If I am going to load up and go wheeling, I want to drive for more than 1-2 minutes.
4) I don't like crowds.
