Ruter's Berry Farm and Garden Center is located on M46 between Breckenridge and Merrill. Every summer, he has rows and rows of strawberries available for you to pick. You can also purchase berries which have already been picked, but those go fast! The strawberries Mr. Ruter grows are absolutely delicious, the best I've tasted in the area.
Then, in the fall, there are pumpkins!! It's always fun to take the kids to pick their own Halloween pumpkin (or two or three).
Mr. Ruter's prices are definitely very reasonable, and you also get the experience of picking your own food, rather than buying it in a generic store.
