Honestly...because it's not that important. T-shirts aren't going to make or break the site...if they do then we're doing something wrong. Secondly and more importantly, my job has nothing do to with marketing...the people in marketing worry about that.
I could help you out in my area if you have the shirts.....
There is a large community of bodybuilders here in Phoenix, but the network isn't organized, thus the shirts would help with name recognition.
