So the book says 10 feet minimum lane width. I just want it to be a track that isn't too big or too small. something that you would expect to see if you showed up at a place on Race day. Especially if I would consider in the future of letting a local club use it. Or if My kids would decide to race one day then they have something comparable.

I drew up a rough idea and from what I can see scouring the internet, an area of ~120x90 seems to be in the ball park.

what all kinds of obstacles are there?
so far I got:
Bunny Hops
table tops
jumps
banked turns
rumble strips

and Id like to make a X-over, but i'm not so sure that would be seen in a real race

The whole track will be dirt, jumps and all with irrigation pipe barriers. I want it to look nice and last and I may or may not be slightly OCD so I want it done right haha
