Does this waterway really go both way at this intersection? Seems unlikely, but I'm not local so I can't be sure. Do any locals know?

golf=hole shouldn't ever be an area, but a straight line (possibly with multiple segments) that defines the optimal path between the tee and the green. Could someone convert these areas to lines instead? The area possibly defines the fairway or the rough, but not the "hole".

This bar doesn't seem to exist according to many sources. Should the identifying information in tags be removed (leaving the physical building obviously) by someone more local?

I don't believe this is the correct way to draw a road. It should be a single way, not two one ways on top of each other.

This Tiger import has a lot of problems. It was done almost a decade ago and it's like there were errors in the translation of the data into the representation in OSM. Tracks bounce from one place to nodes on another track and then back again. Sure would be nice to eliminate all of this and run it again from scratch, but I have no idea how one would do that.
