Interesting facts? Okay, here's one: the flies are SO BAD that it's a frikken hazard. If you're stuck on belay you need a third arm (or third and fourth) to keep the flies from driving you mad. Even true local Aussie climbers have said that they've never gotten used to the flies, so if someone tells you that you will they're lying. The don't bite, thank goodness - that's for the mosquitoes - but they do crawl all over your face, eyes, mouth, nose, ears, etc. Bug spray does NOT work, either.
Good luck, kids.
