With so many bicycles being ridden here it is common to see these shelters to keep the bikes. In the college there are many of these sort of shelters. Rather primitive really, but good enough for us I guess.
Some of the bikes here have almost rusted away - perhaps belonging to someone who has not returned to the college. All must have locks on them as for some reason they go "walkabout" without their locks. Even then some will walk. One needs a solid lock!
You also need to be lucky to get space in the shelter. Some times it is very full of bikes.
