[at-l] Re: heat packs

Campmor has both kinds of chemical heat packs, plus a hand warmer which 
burns some kind of solid fuel.  Most "outdoor" stores have them, especially 
those which sell hunting equipment.  I've also seen them in K and Wal Marts.

The single-use heat packs in my EMT kit came from Galyan's in Indianapolis, 
two for 79 cents.  They are about 2 x 3 x 1/8 inch, maybe 1.5 oz. each.

Lexan bottles full of hot water are great warmers, but these devices could 
be very nice inside wet boots in cold weather.
