It is becoming harder and harder to find pumpkin patchs in the Chicagoland area who do not charge just to get in. However, First United Methodist Church of Oak Lawn, 100th and Central Ave in Oak Lawn, IL 60453 does not charge admission. It is open every day from October 15-31: 10:00 a.m.-dusk, Sunday: noon-dusk. Pumpkins by size not pound! They have large, small and mini pumpkins, gourds, arts & crafts, hayrides, arts & crafts, food and drinks. Beat those expensive crowded pumpkin farms!
