I have a well stocked truck, that I'm not concerned about, what I was asking is that if I had to walk ( travel restrictions,limited fuel, truck brakes down or whatever the reason ) to my Bug Out Location, and obviously couldn't carry enough for the trip, considering there will be 4 adults one limited in their mobility and 3 children. I'm also talking about going to my bug out location, I know if I'm cross country trying to get home I might not have that option, but if it was well thought out as to distance and location on the road home you could also use this option. I checked out a lot of the storage places around here, happy to say there isn't any barbed wire, there is however some with chain link fences, simple enough to cut and enter as long as the shed rented was located on the back side and not easily watched from any surrounding homes or businesses. A lot of them don't even have fences. I guess as some suggested hiding stuff in old couches or chairs, bags of garbage or what have you would be one way, the food choices would be limited for sure, water could be kept in a cooler to help with the heat problem, certainly item's like that would have to be rotated. And as was mentioned being on the one road that you supplies are stashed on might only be 50/50 so having other stashes located within a reasonable walking distance as long as it didn't take you to far out of you way might also be a consideration.
In the story he put a bolt inside so he could lock it and prevent anyone from using the outside lock ot trap him inside, he also had a piece of carpet attached to the door so no light would shine outside as well as a inspection mirror to see if the cost was clear when leaving. There is a lot of interesting ideas in this story as well as all the others. I have been reading quite a few lately. Here's the link you asked for and also if anyone else is interested.

Also as Susan mentioned, I wouldn't use this as my only stash, between here and there, but any that I would select would be within walking distance all withing a reasonable area, there are many routes to my BOL and all are secondary roads and offer quite a few options for places to stash supplies.

Please keep the suggestions coming as nothing is written in stone yet and I value everyones opinion. This is just one of the many things I'm considering. Also swapping storage space with someone isn't an option as I don't know anyone in that direction, at least not yet.
