All aboard! It's time to hit the track at Zube Park near Hockley Road. Families can ride large model trains for free from 9 a.m. to 1 p.m. Saturday. The Houston Area Live Steamers offer free rides the third Saturday every month through November.

Start your Saturday or Sunday with a classic - Mary Poppins. You can watch the movie for free as part of Alamo Kids Camp at the Alamo Drafthouse in Katy or Vintage Park.

Or if you've got a “Frozen” fanatic in your house, head outside Saturday night to the Pearland Town Square to watch the Disney animated musical on a giant screen. The movie starts at 8p.m. Get there early for free face painting and balloon art from 5:30 p.m. to 7:30 p.m.

Our friends at Houston on the Cheap have even more free and low cost ideas.
