HOUSTON -

Forget National Donut Day, Shipley's is extending the party for the whole month of June. Every Friday, Saturday and Sunday in June, you can get a free glazed donut with any purchase.

Start your weekend with a free movie at Alamo Drafthouse Cinema. Both locations, in Katy and Vintage Park, are showing Legends of the Guardians every morning in the 10 a.m. hour from Saturday through Wednesday. The free movies are part of Alamo Kids Camp and you can catch them all summer long. Seating is first come, first serve.

After the movie Saturday, head over to Rob Flemming Park in The Woodlands for the Montgomery County Animal Society's Tails & Trails event. From 11 a.m. to 5 p.m. you can walk the dogs that are looking for new homes and let the kids try out the dunking booth, bounce houses and crafts.

Bush Intercontinental Airport is turning 45 years old, and they're celebrating with a party Saturday from 10 a.m. until 2 p.m. They'll have moonwalks, face painting, a video game bus and a raffle for a set of tickets on KLM Royal Dutch Airlines.

The Houston Symphony Summer Neighborhood Concert series is coming to two neighborhoods this weekend. On Saturday at 7:30 p.m., the free concert is on the west side at the Chinese Community Center at 9800 Town Park. On Sunday, the performance starts at 6 p.m. at the Windsor Village United Methodist Church on Houston's southwest side. Dress is casual. If you take the kids 45 minutes before the show starts, they can see the instruments up close in the Instrument Petting Zoo.

Our friends at Houston on the Cheap have put together a list of "48 Free and Cheap Things to do in Houston This Summer." Nothing on the list is more than $10.
