Visited the Arboretum several times, always doing their spring Bud Run fund raiser until becoming a member a year ago. The different displays in the great hall and lower level art gallery are usually interesting and well done. We've enjoyed the Mill City Farmer's Market there, orchid shows, musical performances, the lovely huge wooden lathe work of a local artist/craftsman, watching the maple syrup process in the spring.
The gardens include a maze for children. One drawback is accessibility, All though there is an elevator, it can be hard work for the elderly to get up the stairs to the building and walk the distance to the elevator. Considering the stairs and distance, it would be great if there were a wheel chair or two available. Also, the limited seats in the great hall make it impossible for an old person to find a seat during weekends or other busy times. We just renewed our membership and use it well!
