Rensselaer County, New York

Rensselaer County is just east of Albany, on the east side of the Hudson River. Troy is the county seat, which has a bunch of well-preserved 19th-century architecture.
The county’s got a good mix of urban and rural areas. Winter sports are popular. For example, there’s cross-country skiing at Grafton Lakes State Park.
RPI, a top engineering school, calls this county home. You can get some great views of the surrounding area from the Grafton Peace Pagoda. Farming is still a big deal here. The arts scene is pretty lively, especially in Troy.
