The only pics I could find of the old Gemini Drive-In on I-75, in Dallas.
The demise of the drive-in in Texas, once a bastion for this type theatres, was a slow but steady inevitability. As the property value of suburban sprawl increased, the demand for these large tracts of land outweighed their earning potential and car dealerships and fast food joints soon won out.
In July of 1934, the third drive-in theatre in the United States opened in Galveston, Texas and by the mid-50s, there were over 400 of them in the Lone Star State. Holding onto the tradition in true Texas fashion, there were still over 200 well into the 70s. Unfortunately, that number has dwindled to only 18 theatres in the state now. On a high note, 7 of these have been built in the last five years, giving hope to all of us al fresco movie aficionados. For a list of many of these theatres check out http://www.driveinmovie.com/TX.htm.
Now, the closest drive-in to Dallas is the Galaxy Drive-In in Garrett, Texas, on I-45, just north of Ennis at exit 255. From Dallas, go 20.5 miles south of the I-20 & I-45 interchange, and at exit 255 for FM 879. They are open seven nights a week and they always show two features for the price of one. They even have a miniature golf course, complete with neon palm trees! Tickets are only $6.00 for adults and $2.00 for children from 5 to 11 years old.
