Dodd's Park was created in 1969 when the Champaign Park District obtained 110 acres. It's located at 1501 North Mattis Ave. It includes soccer fields, a softball complex, a tribute to Champaign Olympic athletes and the Champaign County Worker's Memorial.
The softball complex contains enough fields to host large tournaments.
The park has a number of soccer fields. Go by there on a Saturday and all the fields are used by youth soccer games. Here's a link to the Champaign Park District's map of soccer fields.
