Whilst traveling north on U.S. Rt 19 Saturday, on a pleasant ride through the Northwest Pennsylvania countryside, my spine was continually assaulted by elevated seams in the road, which are too much for my motorcycle suspension to absorb. I was able to see many of them in advance and brace myself, but my passenger/wife was jarred painfully numerous times, and I had to move to the Interstate for the trip back home. It was literally too painful to ride the 2-lane. There was a section on 19 (about 5 miles, north of Portersville) where these seams had been ground down to the level pavement, and that section of the road was certainly pleasant. I don't even know what government agency or department would be responsible for such a task, but I would imagine that many small cars were experiencing similar discomfort over this heavily-traveled main road. Whom would one complain to? I'm thinking, PennDOT. This is the experience that will end my motorcycling days. I really felt that I could be seriously injured if I hit a big one and was not prepared. And I have a 900 pound touring bike. I can't even imagine what it would be like on a Crotch Rocket.
