J.A.F.O you are correct about the S/S + 30 rule, i didnt include that. But what i was mainly pointing out was the extra 41 mins of daylight due to the difference in ss sr times due to location. Totally agree on ending the day with a good meal and a Malt Whiskey, have you tried Glencoe Cask Strength? 56% proof i think, must be taken in moderation especially if you are flying home in the morning!
