KBAZ is the code for New Braunfels Regional Airport. Every public and military airport in the world has such a code. Here are a few:
KAUS - Austin
KSAT - San Antonio
KRND - Randolph AFB
KDFW - Dallas-Ft Worth
MMEX - Mexico City
KLAX - Los Angeles
KJFK - John F Kennedy
ELHR - London Heathrow
ORBI - Bagdhad
RJTT - Tokyo Haneda
YSYD - Sydney
PHNL - Honolulu
Just a bit west of the cache is KBAZ. From the end of the street, you can see aircraft practicing takeoffs and landings. Most of these aircraft are from the flying schools at the airport. If you feel adventuresome, stop by one of the schools and take a "discovery" flight. The schools will provide an aircraft and instructor so you can try your hand at flying.
The cache is a standard ammo can hidden in the obvious place. It is hidden on public land close to but not on the airport property. You will not have to cross the fence to grab the container. Please replace to the exact location to help keep it hidden.
