I would like to spend a day at the NRA convention. I would really like to do it as a pit stop on my way to camping down South. As long as I will be pulling a pop up trailer I am wondering if it would make sense to park the trailer early morning, go to the show, then come back and sleep that night and pull out the next day rather than a motel. I am a little over 2 hours from Indy and will be coming down 65 and then continuing down 65 for my trip. I like to camp in totally unimproved spots as far from everything related to civilization as I can. I figure there is no place near Indy that are unimproved that would be safe to leave my trailer and gear unattended for a day so are there any spots you guys could recommend?
