When I lived in Michigan I felt pretty secure with easy access to various family properties in the middle and northern parts of the LP. Could have holed up in any of those places for a good long time with plenty of land, water, and supplies.
Out here in the Seattle area I feel exposed. Depending on the time of year (like now) it's next to impossible to get over the mountains and even under good conditions there are a limited number of egress points. I've pretty much reconciled myself to hunkering down rather than bugging out should the proverbial SHTF.
It's funny how the new economy has led to such a rapid breakup of my family. We used to all live within a few miles of each other in SE Michigan and everyone had a place up north. Now we're spread to the four winds with most of us in densely packed coastal areas. Not ideal conditions for dire scenarios -- loved ones at opposite ends of the continent in precarious urban areas.
