I don't really leave a 2hr radius of SF now (although I guess I drive to Front Sight and Vegas sometimes, but prepare separately for that), and have all that stuff and more. Case or two of water, some tools, often a range bag with items, etc. Mostly worried about responding to someone else's accident, but there's the lingering fear of an earthquake, big fire, or other event like that. This is one of many reasons I like having my own car vs. zipcar or public transit -- it's 100 pounds of things to deal with emergencies (including "server broke, need tools and some network cabling", which is a much more common emergency for me than gunshot wounds...)

I really want to get into bay area amateur radio and get on some repeaters and stuff. An HT in the car seems like it would be a good addition. Maybe 2013.
