Really informative little institution, great for kids and adults (but maybe more for kids) to visit. Expect to spend maybe between 20 to 40 minutes or so there. It's not a very big place, but there's free parking, it's educational, and views are pretty, even on a rainy day. And no entrance fee (although there is a donations box, they don't pressure you to donate). Definitely worth a visit if you're in town while they're open. They're also very responsive on Facebook too.
