It might come as a surprise, but the Wisconsin Dells is well-known beyond Wisconsin, Northern Illinois and Eastern Minnesota. Over the years, the vacation destination has found its way into comedians' acts, late-night monologues, books and movies. As the Dells-Lake Delton area gears up for another tourist season, there is a definite pop culture influence on new events, features and attractions in 2011. The Tommy Bartlett show goes retro, vampires pop up at Ripley's and the Dells Boat Tours take a cue from "LOST."
