I travel for work and sometimes go to large, secured, Federal sites that don't allow handguns and have been known to search cars entering the gates. I'm in OKC and I couldn't bring my EDC because I'm working on a government site. Is there any place I can leave my gun while I am working for a few hours on Federal property? The only thing I can think of is to keep my hotel room for another day until job is finished, but I can't justify that much expense very often. Maybe I should ask to use the hotel to use their safe.
