Sorry for the late response, i've had some computer issues the past week or so.
Gordon - It was a typo, my mistake.
Bradford - The Cuben is a great idea; i hadn't thought of that. I'm going to be buying most of my gear over the course of a few months (to make it a little more affordable), and that'll put the Cuben within reach. Thanks for the suggestion! As for the cold, i've had to deal with similar conditions before, so i feel like I could deal with it. To be on the safe side though, i'll be doing a few "demo" hikes, and if conditions were truly bad on the trail, i could stuff the bivy to make it more insulated. I've also read of some ultralite hikers who actually do some hiking @ night because of the cold. If i had to do this, i would, but i wouldn't prefer it. The Mapdana is a great idea too!
Spruce Goose - Thanks!
Nate - I'm from Central MA, so i figured the summer nights were similar temperature wise unless one was up on the hills. I could be very wrong though. I've highlighted some of my ideas previously (stuffing sack, moving during the night, stuffing poncho in bivy sack as another layer, etc), so i won't go into lots of detail about them. I've also debated just wearing all my layers (shorts, pants, short-sleeve, long-sleeve) to bed as well. I'll have to look into some ultralight insulation . Thanks for the suggestions!
Larry - Oops, that's on my original list but i forgot to type that into this one, another typo! My bad!
I understand the list is a super-ultralight minimalist list, but i do feel that it's adequate for it's purpose. When i'm not running/hiking, i'll either be eating or sleeping. Nothing else. I'm not trying to be cocky by stating my Eagle Scout rank, or having gone to Philmont "x" number of times, because it's a different ball-game (and i'm a relative newcomer to ultralight packing).
Thank you all for your kind and very helpful suggestions.
