My Chapter (which is National) doesn't belive in branding or tatooing with our letters or crest, but there are a lot of us who have gotten a tattoo of our mascot - my self included.
Personally mine is in a

discreet place which I can cover up, and it was something I choose to do on my own. There are Frats at my school that required branding or tattooing, for us it's not something that is pressed on anyone, but I think for those of us who have done it, there is a sense of pride.
Then again I think we have a way cute mascot - Yay Ladybugs !!!
