Unclog those canals
Don Muang (‘‘Empty promises,’’ PostBag, Sept 24) is right. Every year, our small back canal which feeds Phra Khanong canal is cleared of plants. Not this year. You can hardly see what is canal and what is land. Nothing has been done to correct it, and because of it there may be the possibility of flooding. In 2011 we were spared. This year? Time will tell.
