I ended up pledging Sigma Kappa even though I hate snakes (we've since changed our symbol to the heart and dove), preferred three letters and didn't care for lavender and maroon together (love them separately!)
I actually didn't think the snake was a "symbol" the same way the heart and dove are. Obviously it's important to us and I love that some chapters still use it. But then, i love snakes
