Maybe not too strange but certainly a surprise. Was fishing a river adjacent to a large park when all of a sudden I heard what sounded like a bazillion mad bees about to swarm me. Looked all around and saw nothing. Then, I looked straight up and about 30' over my head was a giant dragon kite 50' long and vibrating in the wind like crazy. It did sound like angry bees. Found out that they were having a huge kite festival at the adjoining park that day.
