I spent my winter holidays in Achenkirch, Austria and took my GPS device with me when skiing (and of course when walking/driving through the village). The outline of the Christlum slopes is now entered but the many holes (rocky areas, forest, etc.) have to be cut out. Furter the slopes overlap with forests that were entered by someone else. So there's still something to do, but at least all the lifts and slopes are there.
