It's not sunny

I've been to a family wedding in Scunthorpe this weekend. Scunthorpe is oft reffered to as "Sunny Scunny" but this is quite inaccurate. "Miserable Rainy Scunny" would be a better description. Now, fair dos, I was there for less than 24 hours and so may have just gone on a bad day. Maybe. I think it's likely like that all the time. Why else would they have needed to call it "Sunny" except as a means to draw unsuspecting people in?
