there's a fine balance between carrying a cell phone as a tool, and using it lieu of being self sufficient.[generalization] I hear so much stuff where people dont' develop skills becuase they have a cell phone - whether it's basic repairs, navigation skills, trouble shooting, awareness of danger.
-If the weather changes, I'll just make a call
-if I break down, I'll just make a call
-if I get lost, I'll just make a call
-if I am in danger, I'll call 911.

etc. This is sort of an overview, not specific to cycling. I think a cell phone is really false security, you need to know how to take care of yourself.
