@enzo I have a friend who was an ecologist at Canterbury. He had an old convertible British sports car of some kind (Austin something?). Anyway, he replaced the windscreen sun flaps that took months to arrive, and drove up to Mt. Hutt to check on some Chinochloa. Says he went over the rise and was gone 10 minutes, tops. By the time he got back the keas had ripped the new flaps to shreds and were hanging out to see his reaction.
