Spinner that's brilliant thank you, I had a yen to take up cross country skiing ( Langlauf - funny how names change) again and my wife fancies "a go" and became a little frustrated with a barrage of information so put a search on here and yours was the only one which came up but with the info supplied obviously the correct one, thanks also for the links. We've to Obernai a couple of times, the municipal is convenient as it's only 25 minutes walk to La gare Colmar or Strasbourg are within easy reach other places too provided there is a station
. Thanks again I can now research in a focused way e.g. equipment hire, aire or site etc.
