If you have never been there and you have any interest in aviation at all you will love it! Last time I was there I stayed here: Indian Trails Campground
It is not that close but we wanted to stay somewhere west of the show as home is Minnesnowta. We did little more than sleep there but I remember it being a nice place. The other time I went there I stayed here: Your Page Title
It is closer but we did not like the campground much. It had little grass and was very dusty and sandy. There was a bar on site which we were parked very close to and the country western was played very loudly until 1 am after which many inebriated campers loudly staggared to their campers. This was about 7 years ago and looking at the pictures on their website it looks like they have made some improvements. Maybe there is someone here who has stayed there recently.
Hope you make it to the show - Maybe I'll see you there!
