(pen) As long as you don't have their washing habits (nil). It's going to get a lot hotter over the weekend but you can avoid it by yet another trip to Heathrow or wherever and flying to "the uttermost part of the earth" (EasyJet, £5). See http://groups-beta.google.com/group/uk.sci.weather Mine is the first post in a thread marked "Cold Stuff". Maybe a bit technical/anorakky.
[pen] To be clear, my disbelief didn't concern the arctic circle vacation (I remember a wonderful trip to Lapland in midsummer) but the idea that 17 degrees is remotely warm, even at 05:30. Even for an eskimo.
