Retired John,
We attended last year. It is a pretty good one and the best I am aware of, in this area, at this time of the year. If you plan to be in FL this winter, or want an excuse to go, the Tampa SuperShow is far better but it's a long way from IN also. Last year we stayed at a motel and that made driving there a lot cheaper. Took the car and had a couple of nights in a motel at $65 per night instead of running all that gas out if hauling the trailer. Show has lots of RVs for sale but also a lot of accessories and other booths with RV related services and interesting things.
