I have dispersed camped in the Hoosier NF. I am pretty new to overlanding and when I camped there late this summer, I didnt even know what "overlanding" was. 3 of the spots that i thought would be great (after looking on google maps, google earth, and ioverlander), all had cables going across the road. The spot we chose was a small clearing right off the paved road. The road led down tona boat ramp, so during the day the road was quite busy. At night it was quiet and DARK. I was using a truck bed tent then, and it would take me about 45 mins to get camp completed. Needless to say, once I was setup i wasnt leaving. Hence, the venture into building my rig for easier overlanding camp setup.
I am in NW Ohio, and there arent a lot of places close. Recently, I spotted some trials on Gaia, around Hocking Hills, but there isnt too many spots to camp. That's my 4 cents, hope it helped a little bit.
