When I moved out here to WY 10 years ago I had the back of my pickup loaded with 30 square buckets (the ones kitty litter come in with snap-on lids) packed with primers, powder, and bullets. I built a 40 x 10' man cave on the back, and am still trying to get things sorted out and placed just right. The buckets, some of which weighed 50 pounds, made carting them around doable. Made the mistake of putting in a 8x4' picture window on the end facing the mountains. Lost 15' to the wife.
