Interesting thread.
There are numerous historic area's, interesting places and places where it is just nice to stop and "smell the roses" so to speak.
There are no official hiking trails but as mentioned numerous sand and gravel roads. Numerous fire cuts that may seem boring, but some do traverse some interesting area's. Numerous old boundary lines, many over grown, hunter trails and deer hunting drive lines. A great place to explore and I agree the best way is to just go without a specific point of interest to locate. I have a gps, I just got a year ago but actually I don't use it until I get home and see where I've been. LOL.
As for cell phone coverage. I have Verizon and the obsolete flip phone, No Smart phone for me, at least not yet. There are area's with no to minimal coverage. What I have accidentally found is hold the flip top part of the phone with your fingers and not the phone body. Apparently like the smart phone of a couple years ago, the internal antenna is weak and by holding the phone next to the antenna a weak signal will be lost. I can have 2 to 2.5 bars showing if I hold by the flip top, then hold by the phone body and watch the bars disappear and the no signal symbol appear. Just thought I'd pass this on. Don't know about the Smart phones, but maybe try holding in different locations?
A question. Why is it only the cabs of the abandoned trucks are present and not the rest? I know of 3 others, only the cabs, 4 counting the one pictured in the 50 fields. Teegate told me of one in the vicinity of the Bryant house ruins I have yet to find, but I haven't given it a dedicated attempt to find. I know of the old bicycle nailed to a tree. There may be what a few think is the remains of a narrow gauge rail road. There are no RR ties or tracks, just something about the trail.
As mentioned Howardsville area across rt 539 is interesting and there are interesting p.o.i. in the adjoining area to the West and of course the Forked River Mts. to the North. Oh, beware of Tom Brown's Survival retreat. There are "survivors" living in hooches full time, including winter. They take a dim view if you happen to wander onto their "reservation" LOL
