In our experience, most recently this reach and the previous one in October in particular, the hustling on the beach has reduced considerably both in amount and aggression. We walk the beach a lot, from Sun Beach north to the AIs and south to Sunnyside and in a cases when we have been approached, the usual, simple, "No, thank you" has sufficed.
We have noticed more of a police presence on the beach, especially this current reach. They are both walking and riding, both daytime and evening time. We were eating at Chances last night around 7 PM and the police mobile came tooling past.
I don't know what other folks are experiencing; but to us the 7 mile beach is the same vibe as it has been for a few years now.
Now about the sidewalk situation........
