Well, I'll be....

A few months back I was stopped at a light while riding home from work.  A truck pulled up in the next lane over and an older man opened his window and the conversation went something like this:

Man: What's that thing by the wheel on your bike?

Me: That's a computer.

Man: Huh, what's it do?

Me: It tells me how fast I'm going and how far I've been.

Man: Huh, where do you read it?

Me: On this screen on the handlebars.

Man: Well, I'll be darned! (spoken animatedly with a slightly southern drawl)

The light turned green and I rode away with a smile.
