Fort Lauderdale was recently listed as 2017's third best city out of 150 U.S. cities by WalletHub for summer jobs, and the 24th best city to start a career in. Arts and culture Like many parts of Florida, the city's population has a strong seasonal variation, as "snowbirds" from the northern United States, Canada, and Europe spend the winter and spring in Florida. The city is known for its beaches, bars, nightclubs, and history as a spring break location, back in the 1960s and 1970s, for tens of thousands of college students. The city has discouraged college students from visiting the area since the mid-1980s, however, by passing strict laws aimed at preventing the mayhem that occurred in the 1970s and 1980s. The city had an estimated 350,000 college visitors for spring break 1985; by 1989, that number had declined to about 20,000. Since the 1990s, Fort Lauderdale has increasingly catered to those seeking the resort lifestyle seasonally or year-round, and is often a host city to many professional venues, concerts, and art shows. Fort Lauderdale's arts and entertainment district, otherwise known as the Riverwalk Arts & Entertainment District, runs east–west along Las Olas Boulevard, from the beach to the heart of downtown. The district is anchored in the West by the Broward Center for the Performing Arts, and runs through the city to the intersection of Las Olas and A1A. This intersection is the "ground zero" of Fort Lauderdale Beach, and is the site of the Elbo Room bar featured in the 1960 film Where the Boys Are, which led in large measure to the city's former reputation as a spring break mecca. The city and its suburbs host over 4,100 restaurants and over 120 nightclubs, many of them
