Miami Beach, once a spring break mecca, is now cracking down on unruly crowds. The city is implementing strict measures to control the influx of spring breakers, including DUI checkpoints and restricted beach access. The mayor has enlisted state troopers to assist with the crackdown. Critics argue that the heavy-handed rules are targeting a specific demographic and damaging the city's tourism-friendly image. The new measures are expected to impact local businesses, but the city is prioritizing public safety.
