This is an 'Observation run'. You are given an instruction sheet with questions and a map before you leave.
You find the answers to the questions as you follow the map route.
Some of the questions are cryptic, so not as easy as you may think.
Everyone meets up at the end, and the one who gets the most answers right wins.
It's not a race, so no prizes for the fastest car.
Easier if you have a passenger, but can be done alone.
