I participated in this!

Alice in wonderland themed game. Clued-up used an app to host a geo-based game where we wandered around to activate characters on the digital map.

Overall story was to free Alice from the Red Queen and save her from being beheaded. All-in-all great couple hours, great for families, great exercise, too!

Parking was meh, but in theory you could do this while driving.

Edit; there were prizes for fastest times, I think. I got 2 hrs, 3 min.
