Lego Letterboxer Letterbox

Oh noes! These Lego minifigures lost one of their friends while they were letterboxing somewhere in Gig Harbor, but they can't remember exactly where! Maybe if you can find the phrase hidden in their photo it will jog their memories!

Once you have the phrase, replace the blank in this web address: http://bit.ly/_______ (no caps, no spaces) to get the rest of the clues!
