Hey: The funny thing is, if you reride the PB300 route form last year this spring, the sand won't be as deep, and there will be a lot less of it. When we laid out last years run, and when I rode the event it self, it was like two different events. After a dry summer and fall the dirt turns into sand.
The first PB300 was held in April and the biggest issue was deep puddles.
I tried to find more pic's from that event, but couldn't. Anyway, go ride the route this spring. You'll love it.
