I just tried to find that link again that explains what the deal is with this strange looking bus. But I couldn't. So here's the gist: That's how back in the days when Ithaca was Holywood and had a big gun plant and a big car manufacturing plant (heck, that must have been very different times!), a tram style transport system looked like that was operating in Ithaca. Because someone had too much money they got a replica made that is now operating as a bus. It used to run on route 10 only but now it's going pretty much everywhere. Here the driver is having a nap near the Cornell Dairy Bar.
By the way, dudes and dudettes at TCAT: I think you wanted to get in touch with us about our route planning thingy. At least you said so a few months ago.
