THE DARKNESS...With the hour just changing I was wondering just how much daylight I will have at the start of the walk in Cornwall, so I nipped over to a favourite site: The US Naval Observatory, Astronomical Applications Department http://aa.usno.navy.mil/data/docs/RS_OneYear.html
This site is not as scary as the address sounds and is in fact very user-friendly. You can plug in the latitude & longitude of anywhere in the world and get the sunrise and sunset information for the whole year of your choice - all for free! (Ooh - I like the 'free' bit).
I have found that at the beginning of March I will have 10 hours & 57 minutes of daylight - and of course this means thirteen hours of night-time) That, coupled with the blustery weather at the start of March, will probably mean quite a few hours investigating the Good Beer Guide's recommendations in the warm, dry and brightly lit interior of the pub.
At the other end, at far off Duncansby Head, I will have 18 hours & 18 minutes of daylight. Just perfect to sit outside the pub with a nice pint, admiring the soft evening sunlight.
