begin cell phone safety rant...
( and this is NOT directed at JOY!!!)
cell phones are a wonderful tool, but they are absolutely useless if you are not in a location where you get coverage. Contrary to popular belief, even if you are in a so-called covered area, you may not be able to pick up a signal. What if your battery is dead, a cell phone is of little use then. I hear so many people using a cell phone as an excuse to not be responsible for themselves...why learn to change a flat, I'll call AAA etc.
this is especially troublesome in recreation issues, people going places they have no place being, unprepared and inexperienced, assuming that they can just call for a rescue if they get in trouble. And they do, and it costs we tax payers big bucks.
