This cache is located close to the site of the old Dalby's gas station, which serviced the Ladysmith area for decades. It is now being redeveloped. Also close by is a new brew pub in case you would like to celebrate your cache find there. There have been many changes in Ladysmith since we lived here in the 60s and 70s, but much of it remains as well, including many historical buidlings.
And once you find the cache location the name should make more sense. I am a fish biologist and this one caught my eye.
