Old-Fashioned Phone Booth

Snapped this photo the other day of my young great-nephew pretending to make a phone call from a pay phone booth in La Crosse's Myrick Park. With so many people now carrying and using personal cell phones I wonder how much longer old-fashioned phone booths like this one will remain in service? This glass booth with accordion doors is the last of its kind in the La Crosse area as far as I know. A real relic . . . the kind Superman used to use to change into his super hero outfit.
