Duncan and I visited the other day, and while we only had a look at the more commercial side of it, namely the merchants' quarter, there are other events scheduled such as concerts and readings. Stores are selling Lovecraft and fantasy-related items, and you can also grab a few freebies if you play the LoveFest Hunt.
Do watch your step though, as the streets of this small New England town are not exactly safe!
LoveFest is open until 2nd September, so don't wait too long. To visit, follow this SLurl.
