Ive been toying with building something similar for a while.
Something to have as a permanent "hide" somewhere, that I could evac to in a SHTF situation, and somewhere to store some kit.
The "pod" would probably be at least partially buried, but obviously I'll need to address factors like air, water, power.
Have considered a rather nifty solar panel but then of course it WOULD be fairly visible to the "undesirables".
Anyone else out there have any ideas for small, emergency shelters? Pics & design ideas would be very welcome.
