I have only ridden in Glamis Ca for the last 20 years, and was wondering the difference in other Sand Dunes, Glamis is huge even with the closures, there really isnt any moisture in the dunes like the coastal Oregon dunes so the sand can be extreamly soft at times where paddles can make or break for a fun ride, the dunes are rolling and long so you dont seem to run into too much traffic unless your in the bowls near the highway, Like I wrote I like to hear about the other dunes my children want to ride in other locations.
