My Dad's a HAM (so's my Mom, but she really just does it to spend time with my Dad), and much as I love him I keep thinking that HAM isn't going to be as useful in SHTF as, say, CB or short wave. More people have CB and short wave, so you can monitor what other people are doing and reach out (if the situation warrants) and possibly reach people.
And, to honor the title of the original post, my prepping today is to start reading "Gardening When It Counts". So far, all two pages, I'm enjoying it.
