The govt. has many pallets of ammo cans up for auction this week at Elmendorf. These are complete with lids and DO NOT have to be crushed. I think the weight is on the order of 15 to 20 tons sold in approx. one ton lots. It will take a while for Alaska absorb all of these and I won't think they are worth shipping out.
Look for bunches of ammo cans at next guns show etc. at some good prices.
