Apparently poisonous water snakes stay on the top of the water, and won't head to the bottom. The one in the picture had the market women jumping as it came vvery close to sliding on board with one of them.
Ken Svey is a resort area with food markets about 45 minutes outside Phnom Penh, although traffic problems can easily extend that to 1 1/2 hours. The road is shocking and very crowded but we had Mr Rich as our tuk-tuk driver taking good care of us. The usual set-up of gazebos over the water surround the lake and you can pay to laze in a boat or go fishing if you want to. The lovely Soriya and I were happy to sit, relax, eat some tiny little bird and have a chat to the passing peddlers. There was a great selection of frog, fish, eggs, lobsters etc available at the food market.
