Size matters?

Mar distance: 1,059 km

To Bermuda Road, 53 km. The butterfly flirts with crushing death as it flits around my wheel. The tortoise in the water keeps a safe distance but looks at me quizzically. The monitor lizard taking a morning swim spots me and promptly submerges. It has the biggest brain and presumably the best instinct for self-preservation. But what about the humans who litter (with non-biodegradable waste, no less) in the water catchment area; what's wrong with their brains? Or the Mercedes 350 driver who manipulates the monster on the road but doesn't flick on the signal lights? Still, I have a nice morning, a partly-training, partly-explorer ride in Upper Thomson and Sembawang to capture sights in case they disappear forever.
