Wow, what a gorgeous boy! Looks like from the rings (at least from what I can count of them) he is at least 15-20 yrs old. And yup an Eastern Box, beautiful aren't they?
I would say in the park with the rivers if you are that uncomfortable with the busy street area. As you know I struggled with the same thing last month. Follow your heart, the answer is there.
And major kudos for saving him!
