I'm not that smart, Russ. And my hand basket was overflowing with glowsticks and frozen treats, like Edwards Pie and pzza rolls. I went back that day and got a very pleasant surprise: they were really 3 for a dollar. So I bought three each of a hi visibility green and a dark blue. I filled one up with cast .59 bullets and submerged it for an hour with no leakage, so I'll be building another kit on the sly. The little woman has put her foot down on me buying any more survival gear until I get lost and actually need to use some of it. She has threatened to drive me out into the country and abandon me like an unwanted dog. And without a cell phone to call for pickup or pizza. I'll be starting a thread looking for suggestions since I have no desire to hijack this one.
