Want to exercise while wearing a large straw hat? Like to watch the sun set while working out? You don't have to attend Harvard to crew. Check out the new recreational rowing club, White Rock Boathouse Inc., which has restored the 1930s boathouse and provides rowing shells--three singles, one double and a racing shell--for the use of members. "Most people don't know how to scull, so we give lessons," says Ginger Twichell. She and club member Sam Leake charge $50 for private lessons, $75 for lessons for two. The shells have sliding seats, so the rowing motion gives an all-body workout. "It's very rhythmic," Twichell says. "You can get in a Zen-like state. It's very quiet out there, and you see the lake from a whole different angle." Membership is $300 per year, which gives you access to the boats and expertise of the members; go to www.whiterockboathouse.com to download an application. "You just reserve a boat, show up and take off," Twichell says.
