There is no reason to look for a hint here.

This is a "permanent" cache intended to remain at its current
location for three months plus one day. Thus the name: Quarterly
Cache.
This cache will be available from April until early July 2010.
Then it will be archived.
I intend to place another Quarterly Cache in the greater Lansing
area when this one is archived. This should provide local cachers
with new challenges, in new interesting locations.
Future Quarterly Caches may take any form: large, regular,
small, multi, puzzle, micro, maybe even a nano.
