I remember you finding those when you were in the area or the Wilds a couple years ago. We've had the AEP grounds on our mind and we've already gotten our "permit". But, a bit too far for the HH commute, I think.
We stayed there last Oct. It is indeed a nice and secluded park that is *almost* boondocking. We chose there primarily because the main HH SP was "full". As it turned out, if we would have chanced it and gone to the HH SP, we could have gotten a spot. But, instead, we made reservations and paid the res. fee (GRRRR) at Lake Hope and made the ~30 min. drive back in the direction of home to go to HH SP.
Keep the ideas coming. We'd like to find a not-much-used boondocking area that we can just drop in to the area at any time. Maybe the AEP sites will fit that bill, I'll have to map it later and see but I think it will be too far for my desire.
