whats to do within 150 miles of sheppard AFB TX on the weekends?

Answer 1

Check the Base newspaper. They will give you an idea of things that are going on in your local area. Otherwise
http://www.texas.gov/ is Texas official online site.
http://www.2chambers.com/tourist39.htm is the Tourist link . Don't know where Sheppard AFB is located at in Texas so click on that and you can see what is going on in your area.
