At first Lisa was reluctant, when we married and she moved in on the property and she become overwhelmed with the stock and redundancy I had in place and my purchasing spree. The house she has in town she now keeps stocked and now she is wanting to go from a 30 day stock to 90 days, what helped getting her completely on-board was asking her opinion and making it count and that I structured our preps around her comfort (within reason) and concerns (kids and animals) I don't get cold easily but she does (very cold-blooded) thus I made adjustments to our preps to accommodate adding a little more weight to our bags with heavier clothing, sleeping bag, communications etc... Going with the attitude 'my-way or the highway' ain't going to help getting a spouse on-board
Yes, I still get the 'side eye' from time to time
