Thanks!
The paved streets are asphalt roofing shingles left over from a project. My plan is to add more, then paint them with some of that roof patch tar and spread sand on it. When the roof patch tar dries, I'll sweep off the excess sand and have a blacktop road. The cool part is, that when a herd of elk comes through Tankland and punches holes in the road with their hooves, they are like an allied bombing run, they destroy everything they go over, I can just cut out that part of the road and replace it!
