Making Memories in the pumpkin patch at Erickson's Petting Zoo of Osakis, MN. Searching for the "just right" pumpkin in the field. So much better than picking on off a shelf or out of a big box in a store. Thanks for all the nice compliments on the size of our pumpkins. Open every weekend until Halloween to get your pumpkins, squash , gourds, straw bales and corn shocks for decorating.
