I got a cell phone when I started studying in 1996 (LOL, a 'mature' student), so that when I was driving to/from home I could ring my partner if I got stuck or broke down...

Then I started work after graduating, and biking and its just piece of mind for me and for my family.

My boys have cell phones too now, and my DH... and its such a relief.

DH has had several rides where he has 2-3 flats and he can just ring up and get a lift.
