I've seen some terms thrown around. Obviously self supported and supported are self explanatory. But what, for instance, defines loaded touring? I do some backpacking as well, but I've always put emphasis on light gear. If I were going to do a shortish 3 day trip (which I'm hoping to do either in the next two weeks or after the semester) then I would picture my load to be maybe 20-25 pounds or so, less if I can buy a 1 person tent before then. Is this considered loaded? Is there a weight limit? Do some people do "ultralight" touring like people do ultralight backpacking?
