A Sculpture and a Bridge

A bench - normal, above the bench a sculpture meant to block the sun. The sculpture is a naked man lying across monkey bars with his dick hanging down.
The Bourne and Sagamore bridges are being replaced - someone should follow the Sydney Australia model and add adventure walks to the financing model. A company could lease the maintenance walkways and get lots of insurance.

Alternate uses for Sugar Maple Sap - Cold plunge pools into maple water, hot tub filled with maple sap, slowly becoming syrup. Soda Stream Sap - like a lemonade stand, collected fresh daily (fuck that's a good one)
