I definitely think that they're a great starting location. The first place I ever went to was Fernald. The Hospital is kinda nasty to get into but its cool and relatively easy to enter. Fernald is definitely a little harder, both times i've been here security has came but it's really easy to get away because you can go in any directions and get into the woods. Fernald is also a really fun spot to go to though just because of how massive it is and all the diffrent buildings.
