Roosevelt Park (Metuchen Rd, Edison, NJ 08837) is a 572-acre Middlesex County park right in the heart of Edison — the largest park in the county system, with athletic fields, the Edison Museum at the park's eastern edge, a pond, walking trails, and the Middlesex County Fair Grounds. The Middlesex County Fair runs each summer, typically in late July, and draws tens of thousands of visitors over its multi-day run — parking lots on Metuchen Road and the adjacent service roads fill by mid-morning, and Woodbridge Avenue backs up heading into the park. For school field days, large family reunions spread across the park's picnic groves, or a graduation party that starts at the park before heading downtown, a minibus or charter bus keeps the whole group together without the parking scramble that makes the fair's last hour chaotic.
The park is also the natural pre-prom photo backdrop for Edison-area high school students, and it is within a 10-minute drive of both Edison High and J.P. Stevens. Address: 1 Metuchen Rd, Edison, NJ 08837. Phone: (732) 745-3900.
