I did it 2 years ago with my sisters we had so much fun they are both well versed in rusty junk and antiques I just love to browse and drool.....had to be careful since I flew in and out. I would do it again in a heartbeat we are talking about next year.
my little advice if you ever want to go is plot it out and make hotel or camping reservations well in advance carry paper towels and wet ones for clean up, be ready for a rainstorm or two and trust me they will be welcome I don't remember having issues finding bathrooms. We learned to not stop at all the individual houses if they were displaying clothes or kid stuff not what we look for and we wouldn't have made it more than 10 miles.
