Lexington MA here...definitely interested.
While it wouldn't be an all day event like Canobie Lake, here are a few ideas:
5 Wits Studio at Patriot Place...it's an awesome interactive adventure, sure to please DISminded folks like us. We have done it and it is something Disney should pay attention to.
Cape Cod Central Railroad - Capetrain.com A special event could be planned to reserve some cars or the whole train.
If you want to do a wintertime meet, then do Bright Nights at Forest Park in Springfield...a very good christmas light display, then head to the Red Rose for dinner afterwards, an amazing Italian restaurant and tradition of ours.
