We store ours outdoors below an overhang in a galvanized steel garbage can and put a couple bricks on it as well. Critters seem to know what's in the can but so far haven't gotten in. If they ever learn about teamwork, we may have to change our storage plan. I did have one time when the lit was left off for a bit and a mouse got in. I found it dead a week or so later. Belly full of seed no doubt, but nary a drop of moisture to be had.
What, if anything do you do to prepare for winter. Here's what I do or have done.
1) insulate windows&pipes
2) buy more food
3) rotate tires or buy new
4) winterize car, truck, tractor, boat
5) store small engines with Stahl
6) get extra anti-freeze
7) store extra kersene&gas
9) stock cold medicine
10) buy new socks and slippers(my favorite)
I use to buy bird feed but squirrels and raccoons soon discover it and you know what happens. I have a few critters here as I live next to the woods, so I let nature be natural, I don't provide. I try to plug every hole I have in the house, but gee those field mice are too clever for me. just rambling -----Willy
