Congratulations, Mark! When I was in school, field trips were cancelled only if the vehicles couldn't go out. We had one surveying class cancelled because it was so cold the oil in the transit froze and we couldn't level it...
I've always been attracted to weather like that - and not only because I'm usually the only one stupid enough to go out in it. To truly appreciate Nature you have to know her in all of her moods. When I was younger I went running barefoot in the woods in thunderstorms. The air is charged, the colours are different, the light... well, you know.
Used to have a little sign on my turntable that read, "Some people don't have enough sense to go out into the rain."
Mike.
