M.G.
There is the Dallas Children's Museum, Planet Pizza (in Plano). You can eat pizza (or not) and take your kids on the indoor rides. There is a very nice playground in Highland Village off of 407/Justin Rd. and Briar Hill Rd (just a little down Briar Hill Rd). It is huge, made out of wood - I think it's called Kid's Castle. We're taking our kids there today. We're also going to Planet Pizza later this afternoon. By reading what other people wrote, I really want to try this Frank Buck Zoo a couple of them were talking about. It seems great! There is also Kart Trax (go-Karting)in Lewisville. It just opened. My 4 year old rides by himself. Your 3 year old can ride with you or your husband. Glen Rose, TX (I think about a 2 hour drive) has some dinosaur exhibit that I have been wanting to try. Also in Glen Rose is a Safari. You stay in your car and drive and watch the animals - giraffes, rhynos, etc. I really want to go, but I have to admit, it scares me. The animals get very close to your car (I think).
If you always want to know what is going on, pick up a copy of a local magazine called Suburban Parent. It says what's going on in Flower Mound, Lewisville, Coppell, Highland Village, and other close areas. You can find it at any Kroger, and it's free. Adventure Kids Playcare, pediatrician offices, and daycare centers usually carry this magazine, too. It is great. They have an "on the go" section, which says what's going on for the month. Go get your copy of it for September and fill your calendar with things to do!
