The Don Mills branch has recently undergone some changes. They have joined the ranks of branches with a mechanical sorter for checking in books. At the moment, they are unique in one aspect. The sorter can be seen by the public! Once inside the branch there is only a glass wall seperating you from this machine.
As wonderfull as this site might be, you must hunt outside for the cache.
Cache is in view of the front doors and a busy street, so plan your visit accordingly. The branch is open Sunday afternoons during the school year, so there's no easy out then.
Happy Hunting.
