Get my hands on the new Photon ReX, test the heck out of it. If it's pulled off right, I'm standard-gifting it to some friends who will really appreciate it.
Put together a plan on how to keep a tank full of turtles warm in a winter power outage...Thinking a smaller UPS to handle the water heater, insulate the glass, stove-warmed water, etc.
Buy some new NiMH cells, the longer-lasting kind. Have a ton of batteries floating around, no testing method, rather hope to burn through them and start fresh.
Get a poncho liner. Not for me, got a friend who uses his more than I use my cell phone, he'd love the sleeping bag option and some extra warmth.
Get some metal cups for my Nalgenes.
Find something essentially useful, but cute and meaningful enough to give my other half on top of the essential nicer gifts.
Get band-aids, Tylenol, Pepto, preferably as much as possible since people always come to me for this sort of thing.
Stash some older clothes away at places where I might need them.
Get together a care package to send to the troops, just a holiday thing.
