Sheesh, I can really relate, Adrian. I'm a good four hours due south of you and have it almost as bad here as well. Today's sunny (a rarity) and almost 50, not as prohibitively windy as it was yesterday, but it takes this late in the day (it's a little after 3pm) for it to be even halfway comfortable to ride and then the temperature starts plummeting as soon as you're starting to enjoy yourself. Very frustrating, and the next day to even have a chance of hitting 50 again won't be until NEXT Sunday. (Which is forecast to be cloudy, just to help dampen any potential enthusiasm.) Again, sheesh.
Just got back from a short, but fast ride. One word: COLD. On the couch now thawing out. Still had a blast. A week of Winter weather forecasted...ugh.. I'll never learn. A half plus century living here and I still get disappointed in March!
