Playing Motorboat: Naperville, IL, July 2008 During our visit with some family, we spent part of an afternoon walking around the Riverwalk located in downtown Naperville. The Riverwalk was built by residents of Naperville in 1981 to commemorate the city’s 150th birthday. While we were resting in the shade of a large tree, Daddy entertained Emily by playing motorboat. Emily loves to be spun around and tossed in the air.
