Hit a rock!!!!!

The Caldon is very shallow and we ran aground many times -what we didn't expect was a hidden rock. We were going along looking at the Boat Inn at Cheddleton ( where we had a lovely Sunday roast) when we read the above sign. I thought very good where is it ------ah we found it!!!!!!! it then took us half an hour to get off the rock with the help of some walkers.A local based boat owner said that the canal over time has moved to the left and exposed the rock which originally formed part of the tow path.
