Too cold to camp?

I woke early so got up and out for a walk by 9am. I still had tea and a read before getting up. I went down the canal, I have to go early on a Sunday as it gets so busy. Not too many people about, a few cyclists and dog walkers. Got to Crooke and spotted this tent by the side of the canal. It was still frosty so I bet it was very cold last night in the tent. 
I saw the kingfisher but he was too quick to take a photo and then he disappeared. The reflections along the canal were superb. I had a lovely walk. My ambition in March is to have at least one walk down the canal early  about 7.30, I might even get a sunrise!
I've started a new jigsaw I spent about 2 hours on it and only managed about 10 pieces, it's so hard. Mainly sky and river. I cant really see differences in colour by daylight so all lights are on. 
Thank you for lovely comments and stars on recent blips.
