Hey, I'm interested in this too - when I relocate Bogie's Bunker to some land out of the city, I'm considering getting something on the order of one of those prefab steel buildings, putting it on a pad, and using it to house some machine tools (this _is_ on topic, moderators - real hard to chamber barrels yourself unless you wanna have a big ol' lathe in your living room...) and other impedimentia of the shooting sports...
I'm in a colder climate - St. Louis, Missouri - Just how much _does_ a garage from hell cost to put in? I'm leaning closer to 20x30 or even larger.
Anyone do this? How'd it go?
