First off, tremendous suggestions and I can't thank you enough.
A few points...
Okay, where can I get those little bottles other than the internet?
Running shorts are underwear.
You convinced me to drop the wool sweater for a light fleece. The down jacket is equivalent to a nanopuff - I wasn't sure I would be warm enough when sitting around.
Spare light, good advice on the photon.
Bear spray I was thinking I should err on having enough, and I know I only need it in Wyoming.
I included a footprint because I was leery of moisture coming through the tent floor when sleeping on snow or frozen ground.
And all of the other suggestions are definitely things I can do. Thanks again for your help.
