Re: 2wd in sand
Like So Cal said, experience makes a difference.
As to equipment, get the widest tires you can get, air them down to at least 15PSI, lower is better, but you can pop a bead. Gears and a locker are good, keep the RPMs up and you have to have alot of momentum. Horsepower makes a big difference.
Dont stop in a spot that you cant get goin easy again. If you have to stop somewhere, stop down hill if you can.
4WD is deffinitely perfered
