I was driving home with my son from austin to san antonio. while driving in new braunfels traveling south past the bucee's is when i saw it. as i came to the top of the hill on the highway, i saw an object hovering silver in color, and cylinder in shape. at first. i thought maybe it was a bird, but it just hovered. as i got closer i thought maybe it's a helicopter or some other plane. however, this object was completely motionless. i grabbed my son's arm and pointed up to where it was, and it was already gone. i have never seen anything like this in my life, and honestly, i wish i never did. i will now spend the rest of my life knowing that i saw a ufo. i'm a military veteran, who knows the difference between a plane, a bird, etc. this had no heat signature, or plume, it was as if it was suspended in gravity stuck. and then bammm!! it's gone. craziest thing i've ever seen in my life.
