I overheard a fellow say that he'd brain anyone that sat on his Harley. He'd had it 20+ years and he was the only one to ever sit on it.
I didn't think that much about the comment -- other than it seemed a bit harsh. Then the other day, I was showing a friend of mine my bike (wintering in the garage) -- they promptly threw a leg over and sat on the seat and stood it up! I just had that feeling, you know? And I understood what the guy was talking about.
You guys ever have someone sit on your bike without an invitation? Does it bug you or not?
