Here's a website about Corbin Park. I have lived near the park for all of my life. The pigs do get out on occasion, but interestingly enough, often times as a result of people "jacking" the fence to let them out! Although the park itself is very private it makes for a beautiful backdrop of UNDEVELOPED land in the Dartmouth Lake Sunapee region.
