Yup, a lot of people don't know about this, but it is pretty bad. Within 25 miles of any US border or coastline, they can actually come into your house without a warrant to look for evidence of smuggling people, contraband, items not taxed properly and basically everything under their regulatory authority. 25-100 miles and they're not allowed to go in your house without a warrant, but they can stop you outside, hassle you, search your car and your person without one. Something like 90% of the US population lives within the 100 mile zone, and the entire state of Florida resides within it because it is less than 200 miles across.
