Hey Ugly Squirel,
I rolled a Super JR. once, went around a guy on the highway to pass him and he turned right into me, no signal light or nothing he was going fairly slow and was towing a feed wagon and even if he would of used his signal light you could'nt see the truck around the trailer any way, I had to drive right off the road into a 3 foot ditch as so not to T-bone the guy, dukes of hazard style, snapped the tung right off my aluminum trailer and sent my grinder rolling. I was a little steamed to say the least. Called the cops and they gave him a ticket and my insurance company went after them. As far as concrete I've seen it up here in WI few times, you will find some brainy smurfs out there, real fun. The cable thing, one time I hit some cable, those lazy pricks only bury that stuff about 3-4 inches below the grass, they don't use a trencher they use a shovel.
