I rode to uni today and locked to the Sheffield stand next to mine was a decent looking bike, it wasn't a total scrapper like most of the bikes at uni. But bizarrely, they had locked it by putting the D lock around the stand, then in the gap between the back wheel and the brake, and under the pannier rack. The frame itself wasn't locked at all. It was so odd, I wrote them a very nice note advising them to make sure that they lock their frame. I don't know if that's the done thing or not, but it can't do any harm. And I was just fascinated by this lock up job, it must have taken longer to get the lock in between the brake and the wheel than it would have done to just lock it normally, surely.
