I live in wi, and am planning on biking across the us to the west, maybe to Washington or CA. I've been into biking but never long distances, the longest ive gone was about 40 miles, but im sure i could do a hell of a lot more, i plan on goin on the trip this summer.
Chck in on the "Touring" forum. Should be lots of help there
Also, you might read some of the current and recent tours listed as separate parts of the touring section - especially David Waggenheim who is currently biking from Alaska to Tierra Del Fuego, and posted about 20 pictures just this week. He is now almost to Guatemala.
