I would like to thank you for taking the time to photograph and post these beautiful pictures. I'm 64 years old, and an avid fly fisherman. My new hobbie is taking pics of mayflies, and I'm getting excited. I've got a new tripod on order, and an excellent camera. I would find it a pleasure to share my photo's with everyone.
