A few days ago you'd swear it was summer already with warm weather, green grass and flowers coming up, and then suddenly it stars dumping snow and rain and the temperature drops to freezing.
That's why you can never plan any form of motorcycle fun further than half a day ahead. Even the weather forecast can't be trusted more than half a day ahead. If you plan to go anywhere in Britain by bike you really should pack like it's a three months trip to the arctic circle just in case. You have to take waterproofs and arctic gear with you at all times even if the sun is out because the moment you let your guard down it will dump foul weather on you without warning.
