I was at the DuPage show in September. I usually go about once a year. You've got your commercial dealers and your hobbyist selling off excess junk. One man's junk is another man's treasure. I find myself spending a little and sometimes getting a lot for it. I enjoy saving and bashing old buildings and it's a good place to find them cheap. Last year I noticed a lot of the older passenger cars going cheap. I guess people are upgrading. All in all a fun way to spend an afternoon. The layouts are mostly the same so not much in the new ideas department.
I did go to a show at Richards HS in Oak Lawn this weekend. Mostly show not much selling. Some very cool modular layouts on display. Again a lot of fun.
