Wow, Kookaburra. I'm in awe.
We only got a couple of inches up here in the coast range, and the coldest was about plus 9 degrees F. Of course, we still have all of it. The roads are still slick enough to keep me and my Schwalbe Supremes off them. I can't get up the hills. I doubt I could get down them, except horizontally. I'm still resisting the temptation to get studded tires for as little snow as we get.
