If you're talking about how to access sand camp 108 you can enter through the day parking lot. Just to get an idea from boxcar campground to 108 is about a 3-5min quad ride.
Just getting the word out, going to be a good showing of bikes racing, anyone els on here going? We should have 8-9 drag bikes in our group, we'll be camped at boxcar campground. Come by and say hi.
