What would you do if you received a cryptic note on your cell phone? Would you sit by while Sherlock Holmes solves the case, or step up to the plate and solve the conspiracy yourself? You?re no passive side-kick like Watson, so let Stray Boots give you and your friends a chance to be the hero in this cell phone-guided urban game.

An organized tour is a great way to discover San Francisco, but a good tour can easily be ruined by a bad guide who sings and dances, or some half-dead zombie who reads from a script and insists on walking in single file. Well, thanks to Stray Boots, boring city tours are a thing of the past!

Stray Boots turns visiting SF into exciting urban games. All you need is a cell phone capable of text messages, a camera or camera-phone, and some friends to play with. Once you buy tickets, you?ll receive an e-mail with a start location, a phone number, and an activation code. When you?re ready, just head to the location and text your activation code to the provided number, and you?re ready to start. ?Come, Watson, come! The game is afoot!?
