Rock Out

Help! I’ve lost my (very smart) pet rock! I last had it within a few blocks of City Hall, but now I’ve looked everywhere and I can’t find it!

Notes:

• To prove you found the rock, place your phone against the rock to scan it. This is an NFC enabled challenge, so scan it like you’re tapping to pay for something. If you are using an Apple device, please use the top of your phone to tap.
• Please return the rock where you found it for the next team.
