Schaake's between Eudora and Lawrence off K-10 is great, the hayride out to the patch is free, its an actual patch, not just a pile of pumpkins, they have a lot of really different types, not just orange ones. We got 5 average size pumpkins, and it was $17, which compared to the grocery stores, I thought was pretty reasonable. They charge 35 cents per a pound.
