Used to but the knees aren't the same now ,we have small slopes here -up to 1km and they are OK but we still do cross country skiing ,they provide lots of tracks and some are lit in the evening for those getting home from work .
Our new house has some about 5km away the tracks are marked and from 2km to 25km and of course you return back to the starting place .
All tracks are free to use and some have a coffee bar ,the downhills can have a almhouse where you can get a warm .
Did you try the blue cheese and ginger biscuits ? If not try to get thin ones if you can so as not to overpower the cheese .
How is the better half today ?
