Not sure whether I should start this here, or in the 'Travel' section, but here goes..
A good friend of mine cycled almost the entire transamerican route from Oregon to Virginia last year, but had an accident (broken collarbone) in Kentucky and wasn't able to wrap it up.
The solution: finish up this year, and take some friends along! I live in Amsterdam, so I'll be flying over in June for a bit of an active vacation. I'm currently busy planning all the details - buying a bike (transporting mine over means spending about 360 dollars on transportation alone, damn airline, and I'd need to swap cassettes and add racks and panniers to a cyclocross that isn't really designed with racks in mind), lightweight gear, sorting a packing list...
The thing that I don't have a real answer to yet is which camera(s) I should be taking along. I've driven through bits and pieces of Virginia on various past trips, and I think I'll probably kick myself if I limit my gear to my Lumix LX-3. On the other hand, a 5DII + 24-105 (and maybe a MF prime or two, nice, light and small) is bulkier, needs better protection in case of a tumble, but is much nicer to work with. I've got full insurance cover for theft or accidental damage, but I'd rather prevent badness.
Anyone here done any cycle touring with camera gear? Will I regret not having anything longer than 105mm when cycling through Kentucky and Virginia? My primary interests tend to be landscape/nature and 'people photography' (candids, etc.). I'm tempted to take the LX3 along as well for handlebar mounting/road videos (it's no full HD video, but it ain't bad at all) anyway.
