We too had a great day out at St Annes. I managed to scupper myself loading a shopping trolley the day before so we didn't bring a lot with us.
Dangerous this shopping malarky. My camera managed to capture some images of the day.
One of my favourites was this picture of Craig's 'Tent City' Manta Ray being admired by an amazed young boy.

The wind was a very light breeze and some of the inflatables were having a hard time of it. In this shot from the pier the wind had just dropped with a number of kites coming to the ground.

Another view towards the pier.
