I once was riding my old Henna Red (orange) BMW K75c 3-cylinder at triple digit speeds up on Mount Laguna at Lake Cuyamaca on a beautiful clear day. I was crouched down behind my cockpit windscreen when I saw out of the corner of my eye a hawk high up off to the right of me. Then I saw it quickly dive down. I was completely blown away when he/she started breaking my direction and then it pulled up beside me about 7 feet away and 5 feet off the ground doing 100+ mph. I turned to look at it and it turned to look at me. I flew that day for real!
