Cly was on an important stagecoach route between York and Harrisburg. The prosperity of
the stagecoach era started to decline in the 1830s with the completion of the Codorus Canal
into York. Also, in the 1830s, a railroad was put in and still runs through it. Today, the only
businesses in Cly are a bar and a landscaping service. Until the late 1990s, the community
played host to a minor league baseball team called the Cly Bulldogs. It has hosted the Cly
Mudcats, an All-star team from the York Adult Recreation League. In the late 1990s, a
developer bought a small tract of land beside the Cly Ball Field, and built Riverside Village.
During construction a Native American burial ground was found. Construction was halted for
over a year while the site was excavated. Between completion and today, one of the houses
has burnt down three times.
