A must-see when visiting New Jersey is the former home and laboratory of the state’s most famous son, Thomas Edison. Preserved under the Thomas Edison National Historical Park, these two structures were where such breakthrough technologies as movie cameras, sound recordings, and batteries first saw the light of day. Highlights of a visit include a close-up look at the labs, vintage movies, and original artifacts, as well as a chance to tour Glenmont, Edison’s magnificent Queen Anne-style home, a perfectly preserved 29-room mansion. Guided and audio tours are available for both sites. Hot Tip: Tickets for Glenmore are on a first-come first-served basis, so arrive early.
