Back in August of 2006 Irene and I were riding on the Genesee Valley Greenway. We were just south of Scottsville when suddenly we were surrounded by what seemed like thousands of Monarchs. It was just amazing. It rained that evening and into the next day so it was possible that the roost might be spending another night. We went the next night this time with a camera. It was one of the coolest nature experiences that I have ever had. The complete set is HERE.
