Today is Sherlock's fourth birthday. Yes he is named after the famous fictional detective because of his insatiable curiosity. He goes by many names around our house, Lock, Lockmeister, Lockinator, Trouble with a capital "T", and assorted other names when his curiosity is out of control. But he's my totally devoted little buddy. Join me in wishing him a happy birthday. Canon 5D Mark II, 1/13 sec @ f/5.0, ISO 1600, 100mm macro lens.
