I personally think glamis is the best spot
For all around fun
Pismo is too small and gets beat up
Dumont is great ,huge dunes but still kinda small ,me and dad can cover Dumont in one huge ride out during the day
Oregon does seem really fun ,I personally don't like the sound restrictions
But glamis is big ,endless ,has everything from small to big dunes ,any rider that's good can ride them
And drag racing is really fun out there ,there's also a huge vendor row and store
I've heard glamis for new years is fun
