I'm Jon. I ride a Honda #16. You won't find me racing, but I'm riding any chance I get. Been riding for 21 years. Been on Pitracer for a loooong time. Lots and lots of good people on here.
Most times they will just tell you to go get the permit if they catch you. Depends what kind of mood they are in that day. If your not pulling a permit, make sure your doing everything to code just in case. They can make you dig up footers to inspect them/etc.
Only thing I can think of is they will probably say something b/c the drywall is a fire block. I would think it would need drywall on it somehow. Best bet is to call Don some morning and ask him.
For me, that's prefect. I'm staying about an hour away right now, if they were open when I could go down, I'd still go. It's a fun place, lots to do, trails are a freaking blast too!
