All around the installation are guides. Each has an extendable pole with a tennis ball on the end. This is just incase the gate loops the loop in the wind and they have to unwind it. One of the guides leans close and tells me "what he really isn't supposed to tell me." Later in the afternoon each guide will have samples of the fabric and if you know to ask you can get a sample to take away. It's a PR coo. Everyone is walking around asking for fabric squares in hushed tones. I got one!
