In the Austin area or in the expensive trendy areas of DFW - a yoga matt bag.. Looks hippie - fits right in, no one questions it as long as you're fit enough to look like you might do yoga.
Nice looking UF ! Thing is with cases like that nobody would believe me. By looking at me you could easily tell that in no way do I play the violin and my cover would be blown. That's why I use the chair bag since I could easily resemble a lazy ass and need the chair so its good cover. Same goes for the tennis racket thing lol. I don't play tennis haha.
I am thinking about stenciling something on the chair bags that says something to the affect of "Soccer Dad" or some other bullshit to throw off the mommys in the area.
I guess if you wanted to walk a country road with your son as he works on his Eagle Scout requirements and did not want to be confronted by police on a MWAG call.
