They can be a lifesaver for sure and are mandatory in my work in case you get hurt.
I know what I did before cell phones,I walked out of the bush lots leaving my truck stuck.
Yep, they definitely have their place. I used to be a salesman roaring around the Prairies, putting lotsa' miles on the company car in a year. Used to wear out a vehicle every year or so. A cell phone would have come in handy a few times (accident scenes, etc.). On the other hand, I would have had to dodge more butt-heads talkin' and textin' on the road. Hmm...not sure if the cell phone would have been good or bad.
TenPenny said it best...it's a tool (and so are some cell phone users!)
