From the event site:
Tech Search Party, San Francisco’s premiere smart phone scavenger hunt, is scheduled for February 2, 2013. This will be the fourth annual event.
There’s no reason to delay, so go ahead and register today. You know you want to.
Apart from the frolic, prizes, and geek.fun, all money raised benefits local public schools.
It works like this:
Arrive on time at the auditorium at James Lick Middle School(entrance is at the corner of Noe and 25th Street). Check in runs from 5:15 to 6:00. At 6:00 pm sharp participants will be given a map with some challenging clues to decipher. Deciphering those clues will lead you to various locations in Noe Valley. When you arrive at the mystery location, you take a photo of the answer with your phone and email it back to an address provided at the beginning of the event.
The first team to complete the clues will be the winner. Here are the clues and answers from our last event.
Why: For fun, mostly. And prizes. And also because all money raised goes toward improving technology for students at three San Francisco public schools, Alvarado Elementary, James Lick Middle School, and Marshall Elementary.
Cost: The fee is $50 for a team of up to 4 and $75 for a team of up to 6. A bargain for memories that will last a lifetime. Don’t forget to come up with a great team name. Be creative; you might get bonus points.
Rules: You’ll need a phone that can take a photo and send email. Be on time, or you’ll be in trouble. Teams have to stick together and stay on foot. Bring a flashlight (or flashlight app). Charge up your batteries. Respect the neighborhood.
