While I do believe in the PSK concept, because of my spontaneity I will often find myself with little more than my clothing, EDC items, and water (in some sort of container obviously). While not ideal, it's amazing what one can MacGyver up with a little know-how and creativity when necessary. With that said....I'm seriously considering getting a PLB. Just in case I find myself in an Aron Ralston kind of situation.

Otherwise, as I get older, I find myself not wanting to carry as much stuff. I'm not an ultra-light hiker, but I scrutinize what I carry a lot more closely than I used to.

Interestingly, the larger the group I travel with, the more gear I'm likely to bring. I figure, with more people, the pace is typically slower (so carrying a little more weight isn't too detrimental) and the potential need for extra gear sinply becomes greater. When I'm with others, I guess I just feel a certain burden of responsibility towards them, even if it isn't really warranted.
