5. An Oddball Day
There are few sights as stunning as a clear night sky in Eastern Long Island, and on Saturdays from dusk until midnight, the Custer Institute observatory—which got a brand-new galvanized-steel dome in 2006—opens its high-powered Meade telescope to the general public for free. Beforehand, though, pop over to North Fork Potato Chips all the way at the end of the Cutchogue Business Center (read big, gray warehouse). During regular business hours, owner Carol Sidor will sell you a case of 24 bags for $18—a sharable, and addictive, stargazing snack.
