Other plans that I cannot disclose
I would probably lay low for a few weeks/months and let all the idiots run around and kill themselves. After that, I would venture outward to look for resources.
Like Scotty, I also have a Chemical Warfare suit which helps with Nuclear, Biological and Chemical hazards.
