it's not the steepest or hardest climb you'll ever make, but we do set it up where no one has made it yet..
the water company has a purge valve up there and they let us flood it with water, in the winter when there's 4' snow and ice it makes it awfuly hard to even get half way..
we do things like see how far you can pull another truck up
drive up in reverse
drag a huge sled full of kids by rope
and much more..
you can't see it because of that house and hill, but it goes down into a rock gully then up into a forest that we've made trails in 200+ acres of our own little play ground..
