I-Park, the East Haddam “art park,” will be opening its doors again this Sunday and welcoming the public during its “October Open Studios” event to meet and view the works of the six resident artists who have been living on the 450-acre campus over the last month. Visitors are encouraged to socialize with this current batch of resident artists (the park hosts several resident groups throughout the year), explore their studios, attend a presentation by the artists, and stroll the art-laden trails winding throughout the property. The event will be held from 2 to 5 p.m. Sunday. Studios will only be open from 2 to 3:30 p.m. The presentation will begin at 3:30 p.m. I-Park is located at 428 Hopyard Road, East Haddam. Admission is free; (860) 873-1306, www.i-park.org.
