I feel ya Gary!
I'm slightly younger (will be 46 next month) and have never owned a mobile phone of any kind, though my wife and teenage kids all have iphones.
When I go somewhere alone (concert or sporting event or DMV etc) I have to plan ahead accordingly, just like you.
It started as a joke back in the day when friends/co-workers would tell me I HAVE to get a phone. Getting married? HAVE to get a phone! Having kids, GOTTA get a phone!
Maybe one day ...
