the washes are every half mile or so. statring from the 78 at wash 1. its just the wash that allows rain water to flow under the tracks. so it starts at 1 and goes to 200 something down to the boarder. Roadrunner is at the very end of gecko, its a pretty good trip to anything good from there, and its all through dune if you want to race. The large closer area has been closed for 12 years. it was supposed to be temp, but the hippies managed to close it for good. Down by buttercup patton and gordons well, it where alot of buggys go. the dunes are not as good as glamis, but theres still alot of guys that go that way. Its not close enough that you would make it there on one tank of gas of a quad though. They ahve always required spark arresstors, they just didnt enforce it. They have their days where they will be dicks about it, and then some days they wont care.
