Glad to hear you had fun talking to locals and had a really nice time!
Unlike a lot of activities where you just roll up and start this activity is better to think of like bowling.. you need your correct shoes on and to get lined up for your success. In the same way you do need to make contact on whats app before the hunt. Sending your team name and photo before the game so we develop a communication style is part of the game so skipping that is not optimal. And yes, although I do tell my hunters they can drive if needed it is true this is an active and challenging hunt that normally includes 1 to 1 and 1/2 miles of easy walking. I believe being on foot is the best way to explore a new place.
As my listing explains it is not a traditional scavenger hunt like any you have done before. It has creative challenges social interaction and being detectives on the hunt. I do host it remotely. I am like a game show host in your pocket. Come ready for something new!
