- A pony keg (a few survive to this day) is a drive-through structure with cases of beer stacked on skids — golden liquid mountains, lining the walls of elongated garages or steel Quonset huts, looming above the consumer […] Our pony keg of choice was on Montgomery Road, on the Norwood-Pleasant Ridge border, a small affair next to a hairdresser's, neatly tucked behind the drugstore at the corner of Quatman and Montgomery.

- Their heyday might be in the rear-view mirror, but the region’s remaining pony kegs still sell cigarettes, lottery tickets, six packs and salty snacks. The Gertz Pony Keg is one of two remaining in Reading, a community that once had six of the little corner stores known for selling small barrels of beer.
