My sand rail is an Appletree 4 seat chassis that weighs in at 790lbs. It's best time at the sand drags is a 4.80. Not to shabby for a buggy that sees the dunes every chance I get.

Buggys are ready and waiting. I should have pulled the stickers off the new tires before snapping the picture.

My friend Dan & I, back when we were racing. I drove the Funco SS1 and he drove the Berrien Lazer. It was expensive and time consuming but the fun level made up for it.

This is a postcard that I picked up years ago at the Glamis Beach Store. I have always been amazed that there are no buggys in the picture.

Grainy substances are so hard to figure out because they're so complex. In a heap of unmoving sand, for instance, each grain interacts with five to nine immediate neighbors all at once. The transitional state, when the heap begins to move, is scarcely easier: Although each grain is simultaneously interacting with maybe only three to five neighbors, those are not the same neighbors from one moment to the next. Even a supercomputer can't keep track of all the interactions.
