I guess my glass is half full. Sure not many choices remain for a LHS, but large craft stores are everywhere and I find plenty of supplies. Stripwood, paint, airbrushes, glue, etc are all available locally. I like the building part of our hobby - from structures to detailing and painting locomotives.
I do agree with Bobby that O prices high. But I for now I find plenty of options to enjoy the hobby on a budget. Plus, I just got back from my first York. Wow! The place was packed!
