After some research into the weather forecast and discussions about what a serious storm warning (level 1) means when you go for bush biking, we decided in the end to give it a try. The decision was a bit late, though, as we found out when we were further up. In any case, this was the first find for the day and because of the accurate coords and the hint, it was an easy one.
