#24 READ A CLASSIC
Books are an endless source of inspiration, as well as a good way to pass a steamy summer afternoon. Start here: "Take off your shoes for a while, unzip your fly, piss hearty, dig your toes in the hot sand, feel that raw and rugged earth, split a couple of big toenails, draw blood. . . I entreat you, get out of those [automobiles], get off your foam rubber backsides, stand up straight like men! like women! like human beings! and walk—walk—WALK upon our sweet and blessed land!"
—Edward Abbey,
Desert Solitaire, 1968

#27 ROCK THE BOAT
If you plan to be on the water this summer, it's important to know how to properly rock—or better yet, tip—the boat. The way to swamp a canoe is to never do it while actually on a trip in the wilderness. If this should accidentally occur, you're in for a world of pain, complete with soaking packs, missing paddles, and soggy misery. Instead, save the drama for the day you paddle back to base camp, where you can empty the packs onto dry land and light the sauna. Then paddle the canoe back out to the middle of the lake, grip the gunwales, and rock the barge until you and the boat go over. This is (a) a blast and (b) the best way to clean a few weeks' worth of accumulated mud and fish guts from the inside of your boat. As for sailing, the worst way to capsize a 16-foot Hobie Cat is to catch the tip of your hull on a wave and pitch the boat bow over stern, sending you like an asteroid into the choppy water. This (a) is hard to right and (b) hurts like hell—especially if you've hit the mast on the way over.

#30 ISLAND-HOP
Maine Island Trail, Maine
Mother Nature must have smiled smugly when she minced the Maine coast into 2,000 islands. Explore this rough-hewn shore by paddling a kayak along the Maine Island Trail, a 350-mile water byway that leads from the manicured coast of Kennebunkport to the 12-foot tides of Machias Bay. The Maine Island Trail Association (MITA) provides access to more than 115 island and mainland campsites. For a two-day taste, start in Stonington, a lobster-fishing village west of Acadia National Park, and hire a guide and kayak at Old Quarry Ocean Adven-tures. Less than three hours at the helm will reveal dozens of microscopic islands, etched with granite cliffs, spruce woods, and berry patches. $45 annual MITA membership gives you access to the campsites; 207-761-8225, www.mita.org. Old Quarry Ocean Adventures: $285 for a two-day trip; 207-367-8977, www.oldquarry.com.
