We have an area surrounded by wilderness and National Forest where there is a small sliver of private land that follows a wild river. The road is one lane in parts and winding so you cannot see who is coming. GPS has sent big rig drivers, large horse trailer drivers and large travel trailer buses down the road with predictable results. They think they have found the shortest route to the coast. The County has even errected a sign warning people not to go down the road in large vehicles.
Just got another big rig a month ago with pipe all over the road as his rear went off the pavement on a turn. Had one lady with a horse trailer and kids pull into one of the tiny villages on the road in hysterical tears.
I know I had a route planed to Yosemite and the lodge warned me that Map quest directions would take me down a 4-wheel drive rut. What is a person to do if they never have been there before?
Just for the heck of it I once followed my GPS directions from the home of a friend in New Jersey. It took me through the most convoluted route through Philadelphia that was twice as long as if I had just used I-95.
