Some places can create strong memories. The following special places are important to Americans who look to the past, but also are thinking of the future.
New Orleans Streetcars
Many American cities once had streetcars, but not anymore. Yet streetcars have been running in New Orleans for over 150 years. The Saint Avenue streetcar is said to be the oldest continuouslyoperating streetcar in the world. Many residents have been riding the streetcars ever since they started high school. Most of them think it's a piece of history. They have these old cars, and they respect them, and they keep them running.
Historic Houses
Historic homes can interest people seeking to connect with the former occupants. A typical one is a very simple, white house in Virginia. This small house in Winchester, Virginia, opened its doors to the public in August. It was home to the singer Pasty Cline, who died at the age of 30. Babe Ruth is considered one of the greatest baseball players in history. He was born in a house in Baltimore, Maryland. With his house visitors are given plenty of opportunities to touch where Babe Ruth walked around.
Havre de Grace
Years ago, Americans used decoys (假肢) to hunt ducks and other waterbirds. Those days are gone. But collecting artful decoys is now popular. Havre de Grace is a town in the American state of Maryland, one part of which is famous for its wildlife. Captain Jobes is one of the top decoy carvers in Havre de Grace. Hunters use decoys to get ducks and geese to come close enough to shoot. The wooden birds are so highly respected here that Havre de Grace calls itself the decoy capital of the world. It also has a museum with more than 1，000 decoys. Most were handmade.
