What do you carry and how do you carry it?

[Duck on Wheels]

I use a camelbak. I can't remember the exact model but it's almost the size of a Mule. (...) small first aid kit, gel, ID,cell phone, and Benadryl (I'm allergic to bees), a tube of Nuun electrolyte tablets, and the all important tube of Aquaphor to relube as neccesary.... ahmm.
WoW! When I think about it that sounds like alot, but it all fits in there pretty nice.

This thread is SO helpful! I've been mentally listing things, then striking some off to save weight. I almost forgot the adrenalin injection kit I too am allergic to bees, but haven't been stung for so many years now that I keep forgetting to carry it. Won't do me much good if it's home in the fridge!

Otherwise, I plan to carry everything in my hydration pack (REI Cascade, women's model, holds 3 liters!). Water in the pack, pedeolyte in a bottle in the cage, small repair kit, spare tube, small pump, cell phone, emergency cash, emergency ostomy pack, sun factor ... which leaves plenty of space to stow a layer of clothing if I need to strip some off as the day and my body heat up. Anything I'm forgetting? Anything I can leave in the car?
