The Big Read: Yes, I have a MySchool card

I have a small mystery in my life. Obviously there are plenty of big mysteries too - we all have those - but the small ones interest me more. My mystery is this: there's a park at the top of Upper Orange Street that I have visited only once. One summer's afternoon a few years ago I took two small girls there after their school day had finished and climbed trees with one of them and patted dogs with the other.
