I went to Walkill with my gf, the kids, and her son this past Saturday. It was a very cool experience. At one point the brother giving the tour asked me what I do for a living. I told him I do mechanical design work and he began to tell me about a project they were working on with a camera mounted on a mechanized device without wires. I forget the application involved, but I thought that was really cool he was telling me about it.
