It would be nearly impossible to overemphasize the significance of the discovery of oil in Texas!
To celebrate this important milestone, your family might enjoy a field trip to Beaumont at the heart of the East Texas oilfields. The Spindletop-Gladys City Boomtown Museum is open Tuesday-Saturday 10-5 and Sunday from 1-5. (Note that they are closed on Mondays.) Admission is a very reasonable $3 for adults, $1 for children.
Visit their website (http://www.spindletop.org/) for more information, maps, and contact numbers.
