Hey Matt, great pictures! Love that pathway!
Just a FYI about the racoons. They won't dig but they can scale those fence boards in a flash. DH and I have actually watched them do it. They hold onto the sides of a board, like you would might hold the sides of a ladder, and up they go. It's awesome and scary at the same time. That's one of the reasons we put a lid on the "secure" pen. It's solid material now, but originally it was the welded wire.
Raccoons can climb the 60 foot tall trees next to our yard in about 5 seconds flat. They are normally tree dwellers and very good at climbing pretty much anything. Good idea to have a cover that they can not chew through or open.
