I'm heading to San Francisco to start a tour of the pacific coast. This is the first time I've ever travelled to start a tour -- I've always just ridden out my front door! So now that I'm shipping my bike via bikeflights.com I'm wondering how to get the rest of my camping/touring gear there. I fit all 4 panniers/racks in the bike box but it's pretty much maxed out now (my bike shop only had the 54" size) and I've still got all of my clothes, cooking gear, sleeping bag, etc to go. I'm taking a backpack on the plane so will be able to fit some things in there (and I'll be wearing as many clothes as possible on the plane) but what do y'all do? Even if I take a checked bag on the plane, I'll need to keep it somewhere while I'm touring. And even though I crammed in a bunch of camping gear in the bike box, I can't imagine the guys at REI are going to want to deal with packing all of that stuff up when they box up my bike to ship it back to Portland. Should I plan on shipping a box back with all of my stuff via UPS? Any advice? Thanks!
