The map referred to another "hidden map". Thus, we first set off for the Hidden Map which would ultimately lead to "the place of sticks" where the rings left by the wizard were hidden. We definitely encountered some muddy bogs along the way and had to do several stops to consult the maps. It was still a bit chilly outside and afterward we came home to a warm bath, but there were plenty of smiles, laughs, and giggles, as well as a shout of glee upon finding the treasure.
The kids are already planning their next quest and I think the wizard is already conjuring another fun adventure.
