Lately, I am using a North Face Yavapai daypack. In it is:
The Canon 20D + 80-200 EF Zoom lens. This is kinda important, albeit pretty hefty.
A book about Ant (not ants -- silly) . The fact that I need a book about ant is proof that I am not actually a geek. All geeks already know ant.
A small tire repair kit -- This typically is used to repair other people's tires, or my own in a dire emergency.
A hair brush -- left over from when I had more hair. Notice the hair bob.
No less than 2 checkbooks.
An Aurora headlamp.
A new copy of Edward Abbey's Desert Solitaire. I gave the last copy to a young woman headed for New Zealand. Hopefully she'll show up one day soon to tell me she was too busy having fun to read it.
Serfas'™ Multi-tool, Spare tube, and 3 tire gadgets. These used to be iron ...
CalTrain Schedule.
Reflective stickers that say Real®.
Jar of Icy Hot®
Registration and smog paperwork for two different cars.
Jar of cod liver oil capsules.
Well, that's maybe too much stuff. At least it's not winter. In which case there would be an extra pair of socks, and shoes, rain gear, and something decidedly warm.
