Travis just told me about the Jack-o-Lantern Spectacular, put on each year in Roger Williams State Park, in Rhode Island. He thought that it might be a cheesy crafts fair, but he said that there were awesome designs there by students from RISD (where the Talking Heads came from.) Travis highly recommends it. I hardly ever make it to the east coast, so I probably won't be going anytime soon.
