Do you have a shotgun ready just in case?
I have a pretty extensive firearm collection, but they're almost always in a safe. I have a room in my basement dedicated to firearms, and the room is concrete blocks with a steel door. I'm more worried about my firearms being stolen (which is a low risk) than I am about using one.
I live in an area with almost zero crime. Since moving here, I'm in an unincorporated township, there have been two crimes. Once, someone broke into my garage and stole a whole lot of tools (picture a box truck worth of tools) and another one was a guy that got arrested for a drunk driving charge down the road from me. The garage was broken into while I was away on a trip. Everyone involved was arrested, including the pawn shop owner from many towns over that knowingly accepted stolen goods. I got almost all my stuff back. The only thing I didn't get back was my battle axe. (It's a long story as to why I had a battle axe.)
I do carry if there's reason to. I can conceal carry (anyone in Maine can, so long as they're over 18) but I figure open carry is more a deterrent.
For the record, I paid for my education by serving in the Marines. I can shoot. I probably won't, even if robbed. It's statistically safer to just give 'em my stuff. My stuff is insured. I like my stuff, but anything a thief is going to take can be replaced - except my damned battle axe, and even that can be sort of replaced.
