What's the location of the dive shop at Buddy Dive
these days? Is their pier back in order or are
they operating from somewhere else? Do they still
have the drive thru fills?

I did a quick read and they are using their own docks again for dive boats. The Dive shop is fully functional there too.

Buddy's drive thru service was not created in response to the dock damage so this service will definitely be continuing.

As of sat July 15, the dock was almost complete ( only the guard rails and some lighting were remaining to complete), the dive shop was back in full operation and they were just about finished adding some needed gear storage area
