I had gotten a stem-top compass for my road bike. I wanted to know which direction I was riding, something that's hard to judge on a path that makes frequent turns. Unfortunately, after a year or two the compass became discolored and cloudy. Being in sunlight made it worse.
With the century coming up (and it's in unfamiliar territory), I decided to get a new compass. If there's going to be more than a light wind that day, it will be nice to know when I'm going to have a headwind, sidewind, and tailwind.
The overall route is East-West, and if I read the cue sheet and map correctly, the second half of the ride will be East-bound. Winds around here are often E or NE, which could be bad news.
Speaking of orientation, I remember reading that at one time, maps were printed with East at the top; not North, as I had always seen. And we use maps to orient ourselves, don't we? So -- is that why the East is called the Orient?
