Don't forget to "seasonally adjust" any bug-out bag.
Get necessary gear while on seasonal clearance, at reduced prices.
Evaluate where you are in terms of equipment and supplies, and in the "Off Season" fill in any voids that you find.
Cold weather gear does get discounted this time of year.
I also like to rotate my gasoline tanks in the Spring and Fall.
I only have three 30 gallon drums but that could get us well out of town or run my 3500W generator for a few hours a day for over a month.
