I always marvel with people who go long distances, like commuting to work, with almost nothing with them. Sure, most of the time your bus or train arrives without delay or incident, you work and return, but...
Yep. I'm going to start taking the bus to/from work starting in october. I will be carrying a Samsonite messenger bag with a Nalgene bottle (32 oz of water) along with my camera bag PSK (poncho, Leatherman Fuse, etc.). I also carry another small camera bag that homes my Canon A75 digital camera. Oh, and another small camera bag with a Petzl Tactikka headlamp, Creative Muvo Micro N200 MP3 player and headphones.
So I basically carry 3 camera bags (without the straps) and a Nalgene bottle. This is in addition to my EDC (Photon Freedom micro, keys & Leatherman Micra) <img src="/images/graemlins/cool.gif" alt="" />
