For me, I go to North Point State park, Ft Howard, Eastern Regional Park. All good parks for bashing. North Point has some trails so that will be nice for just trail riding (not really crawling.
Yea Chris had to close up the track sadly. Way to much for rent.
If you want some other places to check out tracks: I go to RCUA (RC Underground Arena) in Columbia. They just opened up February this year. They got Mini Z, Drag, Drift, and carpet off road/on road. Cody from BACH runs the carpet off road track on Thursdays for racing. Another is 180 Raceway in Middle river. They do carpet on road and they are only open on weekends. Mimi's (The Track in Gaithersburg) has a offroad clay track and fully stocked shop.
Now this reminds me I gotta go over to Chris sometime soon. I need a new servo and I need to see what he has in stock for stuff.
