P.S.
I don't fish - they are too wiggly and slimey and plus the rule is you have to touch them if you hook one and I can't handle that mentally - however, my husband is an avid fisherman and this is what he told me...
If you can venture a bit further out of Spring, we've dropped a line under the bridge in Northshore Park in the Woodlands. There is also WG Jones State Park off of FM1488,about 2 miles from I-45, but you'll need a park permit, which isn't a problem to get. WGJSP has a nice, shaded small pond/lake and picnic areas. Academy sells minnows and the only other place he knows of minnow selling shops is Circle S off of FM2978 near Carraway Dr/Rd/St in Magnolia.
Just curious, what other interesting outings have you done? I am the same but my son is only 3 so our outings are sort of limited. Well, have fun!
