Nice kit!

Gotta get me one of those saw handles...

Just a few hints/ideas/fine tuning:

1.Add another bandana.
2.Ditch the baseball cap and go with a small boonie, sans ziplock. How critical is it to keep a hat dry in Phoenix? I used to live in Tucson and for most of the year I would *want* that hat to be wet for cooling.
3.Two mini bics are only slightly larger than that one regular bic, and give you redundancy in a critical area.
4.Add a triangular bandage. Too many uses to count.
5.Change the ziplocks to aloksak bags (Yep, more expensive, but they are nice and make much better water carriers. Get different sizes.)
6.Add 2 Gerber Breast Milk bags.
7.You need two sharpies? Just wondering...
8.Most medical tape I have been exposed to isn't that great. I'd just use the gorilla tape over gauze or 4x4's.
9.When you can, upgrade to the AMK heatsheets bivy. NIIIIICE...
10. Add a N95 mask and swim goggles. You are in the desert, dust storms!
11. Add an eyewash (at least 10mls) to get the sand out of those eyes.
12.Add a local map
13. Geez, I need to shut up already! Sorry!
