...Isn't perhaps the brightest idea, but hot damn! It's fun. Spent a couple of hours up at the Knab on the rough there. Found at least three different runs- very nice. For those of you that don't know Lerwick that well, this is what it looks like:

I've considered the skatepark out by Gremista, but such things aren't really designed for mountainboards. I was going to go for the track up the top of the hill, but they've gone and chipped it with nasty sharp rock that wouldn't encourage traction, so that's out of the question. If anyone knows any other good spots near, or within walking distance of Lerwick please leave a comment ^_^
