We'll be visiting SDC next month and my youngest (age 14) wanted to invite a friend his age from his troop to join us. His mother told us her son had never been to SDC before and presented our invitation to him. Afterwards, she told us that when she described SDC as an 1880's themed amusement park, he got VERY excited and couldn't wait to go because he loves all that "cool retro stuff!!". He thought she said 1980's.
(Yes, he's still excited about going with us, even after she corrected his misunderstanding.)
