The art gallery is always interesting but the Spring time "Art in Bloom" always stands out when floral artists make magic reproductions of artwork on display. This is accompanied by a Tour of Gardens on the weekend which is always fun.
It's possible to catch some genuinely good shows here, from local visual artists to local drama. I've even been there for a benefit/dance party. The staff has always been "on" with friendly efficiency and old fashioned hospitality.
I've visited the art center several times (from France!) for both exhibitions and events (with dinner etc.) which were usually concentrated on the current exhibitions. They also have wonderful art courses and even on July 4th a great view of the fireworks. Really incredible for such a small town.
