Could be time travel (but if it is it isn't here anymore) About a guy who is going to a gun show and he and his truck travel to somewhere else. The roads he knows are still there but are just open areas in the trees, obviously planned but undevelloped. He gets the opportunity to go home and collect people and gear.I remember Walmart parking is used, as well as a diner. I thought I knew it, but was mixing and matching story elements. Rendezvous was one story I was looking for, but not this one
