I like this tread. I think the safe storage of firearms is paramount. It is an integral part of responsible gun ownership and something we can all do to protect our 2A rights.
I too have multiple safes ranging from cheapo's in plain sight to 2.5 ton AMSEC's (empty) for the more exotic hardware. I dehumidify the room and not the safe. I don't like ANY holes in my safes. Battery powered LED lights work fine. Fire is as much of a concern for me as theft and I don't want any avenue for the heat to get inside. I keep my stamp collection in another fireproof file safe in the bottom of one of the big AMSEC's for absolute protection.
