I used a kickstand on my first tour after getting advice on this forum that it was crazy to ride without one. During the tour, Vancouver to TJ along the PCH, the bike fell over a number of times. The kickstand was a greenfield but if the ground was not perfectly flat the bike would just roll and fall over. One time when this happened, it bent the hell out of my brand new Jannd Extreme front rack when it came into sharp contact with the bikes down tube. I am glad that it was a rack that bent and not the bike frame but still a bummer. After that happened I took the kickstand off the bike at the next town, saved myself nearly two pounds, and happily layer my bike down on the ground where I knew that nothing could happen to it, for the rest of the trip. Actually I rarely had to lay it down, because I could almost always find something to lean it against that was more secure than my kickstand.
Apparently, Surly agrees with me. Check out their article on mounting a kickstand to the LHT: http://surlybikes.com/info_hole/spew..._haul_truckers
