Believe it or not we had rain mixed with snow the other night! That's right its getting cold! Some things to remember for winter; don't store liquids that could freeze and make a mess inside your storage unit. Don't store food, or animal feed, it attracts critters. Use a good disc lock.
This time of year we have wild temp swings, keep good ventilation, use pallets to keep boxes off the cement floors, or a layer of plastic storage boxes on the bottom, will do the same.
This morning we woke to thick fog! Yep we are in Arizona.....hard to believe sometimes! :)
