I am looking to rent a baseball field in September for a baseball themed gender reveal party. Does any one know of any parks in Kingwood/Humble/Atascocita/Conroe etc that rent out their facilities? Or of any private schools or churches that might? Thank you for your help. 

For Kingwood try:
Kingwood/Forest Cove Baseball. They run most of the fields in Kingwood.

Kingwood Service Association: They run North Park Recreation center. I think there are 3 or 4 softball fields there.

New Caney: Ed Reinhart Park has several fields.

Humble: Lindsey Lyons Park.

Good luck and congrats on the baby. 

KSA owns all the fields in all the major parks here. They are leased to various organized sports groups. 

What a cute idea. Congratulations on your little one!
