Someone mentioned the website (blog) www.tashadoestulsa.com on this board and I noticed that she did a post recently about the best pumpkin patches in the Tulsa area. Here is the link to the post: https://www.tashadoestulsa.com/2010/09/pumpkin-patches-in-tulsa/
I've been to Carmichael's when I was younger and Pleasant Valley Farms last year. Both were great, with lots of things for kids to explore.
Hope that helps!
