I think it's awesome that the BGLO's are soo proud of their letters. Especially their alums. I always see their decals wherever I go. Sometimes at alumni/chapter functions I check to see if Chi O Alums sport decals on their vehicles but most don't (probably bc their cars are so decked out!) ~ I will when I'm alum.
Maybe it would help if there were sophisticated nice Alum Decals for Greeks, that'd be cool.
