The students gave their research symposium after brunch and then had free time to explore the island.  I went swimming and sea glass collecting with a few folks.  Then we all went for a hike to the Shoe Tree, where I donated my well-loved PF Flyers (they were falling apart and got stained with seal blood during our dissection).  Then we hiked out to the southern cliffs and got a great view of Star, Cedar, and Smuttynose Islands.  Our evening ended with a screening of Finding Nemo.
