A simple wooden fence at the Norman Bird Sanctuary. The way it was tied on was very interesting to say the least.
I didn't really know this existed. Apparently it was an island at some point, now it's a little preserve. There are some nice views, and it's pretty in the winter.
One thing you can expect to see at the Rhode Island Airshow is the Oracle plane do it's tricks. This is the one where there are strings attached to the two poles and they fly through them at different angles.
I went to the boat ramp by Wilson Park and found a small path and checked it out. There was a spot at the end where you can pop out of the trees and have this for a view.
