This afternoon went back ny to exercise although the dark clouds were already looming at half the side of my area. (The ny side wasn't with the dark clouds.) When I started my stretching on the track, I could sense that the atmosphere was filled with methane-like smell (as what you'll smell in zoos). It must be the fertiliser used to maintain the field. Wonder if it's 'natural' fertiliser or synthesised one. And there goes the soccer fanatics lying and kicking around the field. hahaha
