I found and bought a "Bison" style capsule today - now I've got to figure out what I want to carry in it. I've tried a $10 bill, and I like the idea of the water purification tablets in a silicone-capped straw. And I already have a Spyderco Ladybug, SAKnife (Signature w pen), lighter (mini Bic - tried the Pocket Cricket, but found it too flimsy and too small actual fuel tank), compass, Mini-Fox whistle, and Photon II on my keychain.<br><br>Any suggestions for other items to carry in the capsule would be most welcome!<br><br>(P.S.: I can't seem to get even a small tarp in there!?! )
