You guys were really awesome at some questions I had awhile ago, but now I've researched a lot more and I have some more. I wish I had more to contribute than just questions.

Info:
Bike: Surly LHT
Stock config with spd pedals and Brooks Saddle
37cm x 700c tires
Topeak rear Explorer rack
Blackburn MF-1 Front Rack
Nashburn panniers
and these 37cm Continental Contacts tires.

Anyways, I'm starting my tour in late May of this year from NYC to Anchorage, AK (rough map here ) If for whatever reason that turns out to be too difficult, I'll end in Seattle. Besides those cities, my trip is very flexible.

I'm going to do a combination of stealth camping, hostels, friends and family, warmshowers and couchsurfers. Perhaps I'll sleep in a motel or hotel if I'm feeling extravagant.

Questions:

I have road tires currently, but what would be a better set if I went on the AlCan? Also, what's a reliable tube?

How do I not lose too much weight on this trip? I'm a lanky geek as it is (170lbs 6'4"), how much would I have to eat?

Should I wear glasses or contacts? Contacts are a lot less of a hassle except for 5 minutes in the morning and night, when they could be lost. I'd bring glasses regardless, though.

As for camping, I don't wanna spring for a bear keg or spray and just use the bag in the tree method. And does anyone have any camping tips? I won't exactly be wilderness camping, but I'll be miles from any town.

Should I ship my bike back or take it with me on the plane?

For a tent, I was thinking of the Moment, Sunlite or Contrail from here. But none of them are exactly stealthy looking. Any suggestions?

Stove, woodfire (with some handy firestarter) or none at all?

When I start talking to myself, should I concern myself with the stares of strangers?

Obligatory cheers:
