Cross country skiing Oberammergau

Here in Oberammergau, Bavaria for 3 weeks leading some cross country ski weeks for Exodus travels.  Last year I was an hour up the road with loads of snow but currently here things are a bit greener. Here's praying for some snow this weekend.  The area has approximately 300kms of ski loipes but only about 50 Kms is open at the minute and this afternoon with high temperatures and also some accompanying rain this may get reduced.
