Most trolley parks were built as amusement parks, but the one near Little York Lake was built expressly for family picnics and more modest entertainment. The pavilion was constructed as a restaurant and dance hall and fell into decline once the trolleys were gone, in 1931–32. The park was renamed Dwyer Memorial Park after the county highway superintendent who began restoration of the pavilion and park 20 years later. The lake in the park, Little York Lake, is an example of a kettle lake, one created by receding glaciers. There are plenty of those around here, but Little York is especially small and compact.
Cortland Rep, which now occupies the top floor of the pavilion (which always feels to me like a strong wind could knock it over), offers a nice story about the pavilion's history, complete with a lovely illustration.
