Note from JWR:

A couple of SurvivalBlog readers have written me to mention that they’ve been getting error messages when they first try a search using SurvivalBlog’s “Search” box.This box is located at the top of the blog’s right-hand bar. I recommend re-trying the same search, using the same text in the same browser session. For some reason the second (and subsequent) attempts works fine. We are tracking down the problem, which seems to be with our Movable Type configuration. (Since the problem exists with several browsers and operating systems.) My apologies! In the meantime, please just repeat your searches, as a work-around. Thanks!
