The thing about going solo is that, among other things, it sharpens your planning and preparations, because getting out of a jam depends entirely upon you, your gear, and your capabilities. in some ways, you may even be safer than going in a group and depending upon "group think" to deal with the unexpected.

Going solo into demanding terrain (i.e., mountains) is usually not a good idea. As a responsible climber, I never did it more than once a month....
