Ride to to the border crossing/Algodones Mex for authentic mexican tacos, get your boots shined, pick up that souvenir machete, pray you didn't drink anything with their water..... Almost an adventure 
I Remember that riding on the back of a 3 Wheeler, awesome ride.
My friends & I once rode our little Honda 110's & 125's from my parents house, down 8th Street, crossed the Colorado River behind Morelos Dam, & into Algodones. But we were 14 or 15 at the time.
But i'm glad to see them opening up some of the restricted areas. There is beautiful dunes back in those places. Now if we can get them to do something about the dune pass issue!
