I was curious about Otay Mesa after a neighbor said he saw some people out there. I checked it out and it looks like a good really local spot. You head South on the 805 and go East on the 905. Right across from Brown Field there was a big area where there were a bunch of people riding, looked to be mostly Quads to me. I stopped and asked a couple guys who where riding a White and Yellow Z if the Cops or Border Patrol ever wrote tickets or hassled people out there. They said, no they're really cool, they usually wave. I think I may head out there in a couple weeks to check it out for myself. Also, I saw some websites that mentioned Palm Avenue which was the Offramp just before the 905 where I saw two trucks with 3 quads get off. I went to the East on Palm, but didn't see anywhere to ride, didn't have time to check out the West side so there may be more riding areas off that street as well. I was pretty happy to finally find a place that's not an over an hour from my house.
