What is there to do in the northern Houston area? (Spring, Woodlands, Conroe, northern Houston)

I live in Spring with my wife and 1 year old daughter. We moved here a few months ago and struggle finding things to do for fun around here. I know there are restaurants and places to shop, but that's not always our thing. What kind of things do you like to do around here? Doesnt necessarily have to be up north. Any ideas appreciated. Bonus points for "non-commercial" things to do. Thanks!
