What are plans for .... to be changed.

While we had called the day before and heard 'all clear' we encounter a thin, but compact frozen canal already above the first canal lock.

7:59 Strasbourg Port Engine on
8:30 Lock Strasbourg Nord  
9:09 Lock 51 First lock of the canal Marne au Rhin
9:27 Above Lock 51 nearly one inch of ice
10:07 Lock 50 More ice, sounds like breaking glass when we drive
10:34 Lock 49  
10:55 Turn-bridge Vendenheim The activation mechanism is frozen solid
11:38 Lock 48 over one inch of ice
12:20 Lock 47 Door opens only after the lockkeeper clears 2 inches of ice
12:46 Above Lock 47 Too much ice, we find 2 bollards, and call it a day.

 The picture shows our mooring space for the night (winter?).
