Incidentally, I'm writing this from home so, obviously, I've always found a way to get back.
I've had problems with very small debris (slivers of metal think like a pick of a staple) caught in the tire. They are nearly impossible to find unless you know where to look. If you inflate the tube with quite a bit of air, you can find the small hole and match it up with the tire to find the cause. I've seen people use half or all of a cartridge just to find the source. That's why I think a combo mini/CO2 inflator is the way to go.
