Long article on Cell phones in Yellowstone and Glacier

My daughter/DW harassed me for years to get a cell since I had a heart attack in 02. I do a lot of hiking and golfing alone so I realize they were trying to protect me. After about 5 yrs of this I gave in and now have a fine cell phone that I take everywhere I go. I may use it once/twice a month to call DW and ask if I need to bring home a loaf of bread or something. Our grandson travels with us all summer long and he calls his Mom every night to stay in touch and tell her what we're up to so cells do come in handy for some. :B
