Thanks for the book suggestion, I'll check it out when I get the chance.
I've updated a few things on the list - returned my synthentic jacket to REI and picked up a down sweater. Also found a clearance headlamp that weighs 2.75 oz instead of 6+. I was in the whites this weekend and actually found my camelback had a hole (that leaked all over my bag....), so I replaced it with a 70 oz platypus. Also ordered cap2 top and bottoms, so I've shaved off a pound or so with those upgrades.
Katy, thank you so much for all of those responses.
Really good to hear that it's bug free - I'll think about dropping the net to reduce clutter, although at ~1 oz it's a minor item that could be essential if we stay at a buggy spot, especially since I don't carry any deet.
I think I will bring a little sunscreen, I have the cap 2s in case it's really bad, but I am generally pretty good about not getting burnt. The only sunglasses I have are Ray Bans that I'd rather not bring to the woods - are bad quality sunglasses even worth it? I've heard a possible myth that poor lenses are actually worse for your eyes since they dilate your pupils but don't actually block harmful rays. Not sure what to think about this.
I'll probably try to grab a cheap straw hat at a thrift store, the $40 REI ones are ridiculous.
My friend's stove is a whisperlite, so we won't be using canisters (although I own a pocket rocket). I think since most of our food is just add boiling water, we will be able to just boil a pot of water and all eat together.
As much as I'd like to rent a bearikade, it's significantly cheaper to rent the big black box from Yosemite. Also, my friends (who are not really concerned with weight) are renting from Yosemite, so it will be much easier logistically. It is a significant weight savings...but I think this time I'll have to pass.
Sani is a must - I have that, just haven't weighed it and added it to the list yet.
Entertainment suggestions are good - a deck of cards and a book will definitely be travelling with me.
Edit: another question, about food: I've planned for ~4000 calories/day, with almost everything above 100 cal/oz. I'm thinking this might be too much food? I'm 20 years old, 160 lbs, in good shape and we're planning 12-18 mile days.
Thanks again for all your help!
