Assumptions
Yesterday a friend of mine asked me about how to plan for watching sunset. One obvious way is to get to a desired spot 2 hours in advance and stay put. The assumption is that you have to get to a particular spot at the time of sunset to watch sunset. However if you have a stretch of west-facing beach that is over 30km in length, there is no need to optimise. Just go and when light changes, stop and watch sunset. Life is simple as that.
Others' principal worries may sound like a fuss to one. Life is hard.
