Just wondering if you all have a general field concept in mind ? I know you mentioned clearing some of the land. Once vegetation dies down that should be a good time to do clearing. Just some ideas to think about: connecting trails between areas (POW camp, ect.), communication tower ( lone, tall,straight pine tree, topped out and painted gray would work), below ground, dug out bunker (tires would be great for this), wood platform between a fork in a tree makes a good sentry point (I saw at least 2 trees that would work) Just thinking ...
I can probably come up with some old CTV antennas.
