There was an old woman from Phnom Penh who liked to canoe now and again, but boating Tonlé Sap -- despite compass and map -- she'd forget which way it flowed, now-and-then.
[Note: The Tonlé Sap is one of the few rivers in the world that changes its flow each year due to the rainy season surge. (As opposed to owing to daily tidal surges — which are more common.)]
Fun fact: Instead of a dry season and a monsoon (rainy) season, Angkor has a rainy season and a rainier season. That is, there’s the Northeast monsoon season from December through April, and that transitions into the Southwest monsoon season that picks up from April through November.
