I would say beach front property gets a lot more of the insanity from my experience in a coastal town. 
Our previous home on the river saw a lot of people hanging out on the shore right behind the house and making use of our stuff.  Technically, the shore of the river is legally open to anyone (regardless of the fact that my property line ended in the river)  and if someone asked first I'd even let them cross my property to get there provided they leave our chairs and such alone and pick up their trash and fish hooks.  But I can't wrap my mind around the mentality too many have when they make use of private property as if they have the right.    You can't leave your kids sleds visible or they will steal them.   They will climb fences and gates and one built a snowman in my neighbors driveway.  Right in his way.    He enjoyed running it over as he was making them leave. 

At least the majority of the insanity will be over after this weekend.
