Went out twice today. Needed the quiet. In the morning went just past the Wat Krathum Sueapla temple to look for the beginning of another small klong going north. Found it; it's called Klong Thap Chan and on Saturday I had reached it via another klong quite a distance to the north. Below shows where I got to.
So today here's a picture of the southern end of Klong Thap Chan. I will try and fill the gap over the weekend.
