If I had 60 seconds and absolutely had to haul buns, assuming I'm already dressed:
(1) Grab .38 and some extra shells. The .38 goes in back pocket, shells go in edc bag.
(2) Tie light goretex parka around waist, don ballcap, throw edc bag on shoulder, grab a couple liters of water.
(3) Exit.
(4) If taking the truck, add 1 shotgun.
Were I not already dressed, I'd light a smoke, heat up a cup of coffee and wait for the end. When not at work, I hate to be rushed. It's a personality quirk -- what can I say?
