Urban 'hike' where a team's direction is decided by the toss of a coin
Coin for team to flip, local street map if required
Patrols or teams of scouts go out for a walk round their local area. When they come to a junction they must toss a coin, heading right on tails, left on heads (or straight over/right depending on junction, etc). The teams are given a time limit, boundaries (eg. no major roads, 'undesirable areas', etc) and if you think it's neccessary a map to aid return! The team that gets the furthest wins. Teams can be tasked to take photos of items or a scavenger hunt to make it more varied.
