Hand sanitizer, an after-bite wipe, and a poison ivy wipe (wasn't sure what else to call this ... it's a wipe to use after you are exposed to poison ivy, oak or sumac). If there's room, replace the emergency poncho with a better reusable one. We have ponchos we bought on clearance from the local college bookstore. bright orange, nylon or similar type material, packs super small, though admittedly not as small as those emergency pocket ponchos do.
Gret ideas Mark! I picked up a mini purelle for him today and am on the hunt for a better rain jacket. He's got a good emergency one in his canoe and hiking packs but I'd like one just a bit smaller for his psk. I'd forgotten about the after-bite and poison ivy wipes. Good call! There's lots of poison ivy in a lot of the spots we visit so better safe than sorry! (We were at a local park for a Pack model rocket launch this week and as the kids ran towards to bush to retrieve the first one, one of the leaders yelled "Don't go in there! There's poison ivy!")
