Looking for ideas for a Funkhana event

Suggest you contact clubs such as Toyota Landcruiser club or nissan club. They have events such as cruiserkhana etc and incorporate fun events in their programs.Many other do the same. Regards john y

Leaky bucket.
Drill some holes in the bottom of bucket. The driver fills the bucket and hands it to the navi who holds the bucket out the window, the driver gets into the car then drives the course stops gets the bucket off the navi and empties into a measuring container. The person with the most water at the end wins.
