Some interesting data, according to
this website Lubbock is the tenth largest city in Texas with a population of over 266k. Bigger than Waco, Abilene, Tyler etc. Who woulda thunk? Is it just Texas Tech students and faculty?
Regardless, its pretty much ground zero for zoo nerds. The only thing I could find in the area remotely resembling a zoological facility is Science Spectrum which has a little aquarium and maybe a few common herps. This would be how far away of a drive a resident of Lubbock is from real zoo:
1.5 hours from Amarillo Zoo (a small zoo)
2.5 hours from Abilene Zoo
2.5 hours from Spring River Zoo in New Mexico (another small one)
3 hours from Living Desert (the one in New Mexico, which is small)
5 or more hours away from El Paso, San Antonio, Dallas/FW, Houston and Austin as well as ABQ or OKC areas.
