Going with my dad to The Owl, a local bar in Canon City, where we'd eat cheeseburgers and play pool until they closed ... The Owl's still there. Dad isn't.
I remember 4 numbers total from my childhood. Mine, my grandmothers, my best friends, and the Wagon Wheel Bar. Lol. 5406 btw. And we only had to dial one number before the 4, not the whole 3 digit prefix. Played a lot of pool and pac-man there growing up.
