I can trim over a pound and a half by dumping the n810 and the inflatable sleeping pad. I had planned to take the n810 for work since it allows me to use SSH and google docs, but I'll just have to keep work from following me. I guess I'm also paranoid about sleeping cold and just need to get over it since a 32 degree sleeping quilt and the 1/8" foam pad should be plenty adequate for summer trips. Now the only thing that needs to charge sometimes is my phone, and I imagine I can swing outlet use every 2-3 days while eating at a restaurant or something. I won't cry too much if my phone doesn't work.
Now I estimate that I need another pound and a half to reach my goal. I'm still not ready to part with my lock, I AM from Boston, after all! Maybe it's a good excuse to find a lighter tarp like the BMW small nano tarp. The poncho function is pretty useless for biking.
