If you look at a map and the road you’re wanting to go looks very windy, you heart beat goes up, doesn’t it. And if that particular road is marked « green » with a coloured line next to it, it means the scenery is very beautiful, which makes you’re heart beat go up even more.
That goes for me a biker, who genuinely enjoys riding. Sunshine, no traffic, uncountable curves – I love it. As in for the scenery, see for yourself (picture above).
