There was a similar post the other day where someone thought they couldn’t flying due to danger zones. Not sure if you have checked out Drone Scene yet, it’s in the link above that @milkmanchris posted. It is the #1 Swiss Army Knife for UAV pilots. I have added a screenshot below of your area, pay particular attention to the enabled filters - these are all you need.
As you can see, you have a shed loads of places to fly 
Yes, and had a hell of time flying there
It can be a little overwhelming when starting off, especially where you can and cannot fly. If you use Drone Scene, you’ll be fine
