Anyone who wishes to participate can pick up a “Find Waldo Local in Hudson!” stamp card, which contains the names of all the participating sites; with each Waldo they spot, they can get their card stamped or signed by the participating shop. To make things a little more challenging, there will be one slightly different Waldo hiding in The Spotty Dog. Collecting store stamps or signatures at twenty or more businesses will entitle diligent seekers entry into a grand-prize drawing for Waldo books and paraphernalia. Happy hunting!
