I had climbed the hill hundreds of times before in all kinds of weather so I am pretty used to it but this morning I found myself running out of speed fast, an omnious moment of equillibrium, and an accelerating sensation back down the hill. I catched a snowbank with the rear right tire that pivoted the left front into the snowbank on the other side. Once I stepped out of the car I had to think quick and took a surfers pose as gravity took me all the way down the hill, so at least my tires were better than my shoes which had done me so proud earlier in the evening in the bowling alley that was the streets of Gothenburg.
After an hour trying to salt and sand the road we gave up, left the car on the now apparently 2614 mm wide road and went to bed. The operation resumed at 09:06 and one hydraulic jack, more sand and 20 minutes later we had put the Astra back on course and successfully accomplished the mission, which makes this a WIN!
