The OP is well taken. However wilderness gear isn't only useful in the wilderness. When a hurricane slammed our state years ago some of the most popular items were backpacking stoves, since electricity was out and natural gas was shut off. A sleeping bag is a wonderful thing to have when you're in a hotel in Nebraska that doesn't have heat due to the situation. Being able to purify water is just as valid when the municpal supply has been contaminated with floodwater as when you're in the woods.
Myopia works both ways.
You're so right, Glock. Losing power, heat or water at our bug-out locations is well with-in the realm of possibility, and another illustration of how my GHB and BOB keep growing. About once or twice a year I strip things down in terms of contents and weight, but it doesn't take long for it to creep back up again.
