Red Sails - but not in the sunset!

It's many years since I have seen a remote controlled yacht on the large pond in Queen's Park. It was dry for the launching but fairly soon afterwards the rain started and I had to head for cover with the dogs. I knew the yacht was a must for today's blip .... the number 21 - the age of one of my nieces, the number of my house and the number of years I have been in this house.
