We used to have some very good surplus stores around here, too...until Waco and Ruby Ridge, which garnered so much negative publicity that they eventually closed shop. (Thanks again, Slick Willie and "The Wicked Witch of the West Wing")
Since then, it's been either mail-order, E-order or an occasional find at one of the floating "flea markets" (one that only opens on weekends here is frequented by the man from whom I got that knife, and he has access to every possible brand at a HUGE discount...feel like a kid in a toy store!)
BTW, 1988???? Your MREs are outdated, sir...you need to replace them (5 year max on those). You may wish to recheck your first-aid kits, too, esp. those which have atropine injection kits; a set of EMT "blunt-tip" shears is always good to include, too. And don't forget the Ranger/SAS "meatball" surgery booklets..read, retain and be ready to "do it".
And to all interested, don't skimp on the outerwear..get goose-down and Gore-Tex outerwear, and mil-spec polypro underwear in addition to the regular clothing.
