I have not one but two (working) watches that I take along when I want, mainly to help me to make sure I get back home when I promised. It seems like there are clocks everywhere anyway. My wife has a cellphone but barely uses it. Too complicated. For my part, I don't want to be constantly "on call." One reason I go hiking is to get away from it all--or most of it, anyway. For camera purposes, I am uncertain. But the popularity of cellphones means there are almost no pay phones anywhere now.
Thanks for the comments. I was afraid nobody had noticed that I'd posted a photo. I actually had photos of my hiking nude but lord knows where they went. They weren't worth seeing anyway.
