Mario, I talked to a friend who has ran there, and these were his responses.
1.) good size, not huge, but comfortable. probably 130-140 run line with wide corners.
2.) no drivers stand.
3.) there is no sub floor under the track, so there are some pretty un-even places, dips, and bumps that seem to upset the car pretty good.
4.) not enough pit spaces for a larger turnout.
5.) they run nitro cars indoors also, but there is no sound deadening material, so if there is one running in the building it is really loud.
Overall the track has potential, but it needs some work before it is race ready.
