One of my favorite books in childhood was 'Three men in a boat' by Jerome K Jerome. The adventures of three guys with their dog Montmorency (can never forget that name!), and their journey through England on the river Thames. Such fun.
It's pleasant these days with spring setting in, flowers blooming, birds chirping, we thought of walking down to Kings Cross for lunch. Walking by the Regent's canal is lovely. The sun peeping out from behind the puffy clouds, making the waters sparkle. Pretty boat homes lining the canal on the sides.
Further down, there are boats you can hire, to go to Camden lock. There are these cute little corners and patches of grass in between where you can spread out a towel and soak in the sun and read a book. Live music, doggies day out, cycling along the canal... it all looks like something out of an Enid Blyton book.
