Slip Sliding Away

I've been in most of the day as I had to wait for an electrician(don't ask). He finished about 4pm, and as the grandsons were here I offered to drop them off for their swimming lesson, so I could look for a blip. I didn't have to look far, as this was taken outside the Cardiff International Pool as I was dropping them off. I thought the huge slides would make a colourful blip.
