I took a long bike ride last weekend with camera strapped to my back. As I was riding down the lakefront I noticed a dog jumping into the lake. It was an amazing sight. The dog's owner would simply point and use a dog whistle to get the dog ready for liftoff. He jumped about 5 times for me and it made for some great photos. Keep an eye out along the lakefront. The owner said the lake was the dog's happy place.
