Theodore Roosevelt's testosterone-laden tribute to hunting, oak, and all things manly still stands on 100 gorgeous acres overlooking Long Island Sound. His 23-room Victorian estate, the so-called summer White House from 1902 to 1908, has been preserved just the way he liked it -- full of books, animal heads, skins, and exotic treasures -- and visiting is a fun experience that also gives you some good historical insight. The home reflects his travels as a Rough Rider in Cuba, big-game hunter in East Africa, and fearless explorer in the Brazilian Amazon. You must take a guided tour, which leaves on the hour and lasts about an hour. On summer weekends, arrive early -- tour tickets tend to sell out by afternoon.
