My Lovely wife and I (back when she was merely my girlfriend) used to stop near here at the old "Fast Stop" for refreshing beverages while traveling from town to town to visit. She would refill "squirt bottles" from the fountain. It's a silly thing to remember but I remember it nevertheless. 26 years and two kids later and she hasn't yet figured out that she's out of my league. She even goes geocaching with me.
Update: 31 years
Bummer that it closed due to the highway realignment.
Safe and easy to get to. I'd call this a P&G. It's just feet from the road.
