Thanks all for the useful feedback! I'll definitely watch the food carefully. My first food package, already in the mail, is too heavy, but that might be a good learning experience. :-) I'll definitely start out light.
@ fastfox - I'm right there with you, 158 with a very fast metabolism.
@ moldy - Yep, a little OCD. However, I've found when I put it all in a spreadsheet and see how much crap I'm carrying and what all those little things add up to, I'm more likely to cut down. Looking forward to dropping 8 pounds!
@ Venchka and Dogwood - Got it on the mountains and warmth - thanks! I was focusing on GSMNP because I'll meet my wife there. But I see that there are many 5K+ peaks ahead. Hoping for a warm Spring!
@ Boogie - Yep, I've learned that lesson before! My mini multi-tool has a scissors.
@ James - Excellent ideas, thanks! I don't plan to take my phone out of my pack and turn it on very often. My Nano is very light and energy efficient so that's my music and books. Perhaps I will drop the camera, but I like it on my pack strap where I can grab it with one hand and snap photos fast. And I was waiting for comments on the inReach. :-) That's just so my family and friends can follow my track. I won't be pushing that SOS button when I can dial 911 if really necessary.
