Yep, I put Yellowstone into the "Not much we can do about it now" category. It's really an event that you can only prepare for generally. Beyond that, I don't have access to the sort of resources I'd need to really mitigate such an event. You just hope you survive the initial blast and debris storm, and then apply general survival knowledge after the fact as best you can.

The one thing I did manage was to relocate to a place where the inital impact would hopefully be lessened. That and I do have access to some rather hardened areas here that I didn't anywhere else in CONUS. Whether I can get to them in time even locally will still be a risk.
