I've gotten to where I try to avoid wearing anything that displays the brand heavily. Since I ain't getting paid I don't want to advertise. Most of my hats and visors are courses, SSC, NLU, or TGJ. Shirts and pullovers are realtively plain or Bama (where I went to grad school), UK (grew up a UK fan), WKU (undergrad), or courses. Only course I rock that I haven't played is my boss got me a pull over from the Old Course.
Now, I definitely don't abide by the one logo rule.
