I fell in the canal with my bike!

not fallen in but been in many times with my old work (laburnum boat club).
if you are down by the canal and see the kids kayaking, look for any with a neoprene spray deck on and ask them to try and find your lock for you. they love going over once they learn how to roll.

i would return quickly to where you went in, because boats moving past will churn up the bottom as the larger ones are often scraping along the bottom anyways, and the lock can move. if you go down in the morning of a hot day (before any traffic) you will find the water MUCH clearer.

I love cycling past Laburnum boat club as the kids are always having such a great time: even the girls with fancy hair and nails. Really cheers me up!

Thansk for teh advice on the lock and murky waters. My husband is trying again today with his Massive Magnet as he has immense pulling power.
