I've stopped a few times before. Once there was a vanagon about 1/4 south of exit 20 in Cleveland. I stopped and the dude was in the back reading a book and said that a tow truck was on the way. He refused help so I rolled. At the October meeting, Matthew showed up kinda late and said there was a broken down bus at the split. We rolled out and met up with the guy. He ran out of oil when a sump bolt worked its way out. I offered to get him all the parts or grab the bus tow bar and yank him home. He said nah, he had a buddy on the way with more oil. I guess he got home!

I haven't had much luck in helping. Maybe one day...
