Hey Ron, you definitely need a beer rig like that to survive the Texas heat. Congrats to your friend for his home brewing skills, I don't have the patience(or time) for the home brewing process.
I believe you are fairly close to Austin where my son recently moved to pursue a a career in music. He can confirm the heat of a Texas afternoon beats what we have here in Pennsylvania by far.
Here's my Bib Bob! Got it at a garage sale for a dollar! Gets attention when you set it on your table at a tackle show!
I always wanted to tie a rope to it and throw it out into a local pond, tie the other end to a Musky outfit stuck in a forked stick, and sit back and wait for other fishermen to notice it! Every now and then tug the rope a little and shout out "Hey, I got a nibble"! LOL.
