I had "the call" yesterday, but it was actually to take me to the LBS and back so I could fix the flat. I had everything with me, except no pump (I keep one at work, one at home, and havent bought a frame pump yet), and the only CO2 cartridge I had was empty. The call to my roommate ended with him being able to take me to the house, but not by the LBS

Completely my fault, and actually today I'm in the same situation as I was unable to find a CO2 cartridge or a frame pump in Big Kmart (the only store I got to on my ride after I fixed the flat when I got home before it started storming).

Wish me luck that I dont get a flat! I'm actually riding home on a longer route this afternoon to pickup a mini pump. Also gonna try to get some more CO2 cartridges... those things are a dream!
