Shore bird

I have barely seen any birds for months - wildflowers have been my main focus. I thought this was a Yellowlegs, but now I can't decide if it might be a Solitary Sandpiper. How embarrasing - I feel as if I am back to square one with birds, needing to learn everything all over again, LOL! Help! Note on 12th September 2007: thanks for the ID confirmation, Danny (DJS Photo) and David Trently!
