Am I too old to rush a sorority?

[xoharlow]

So I will be transferring to the University of Northern Colorado as a Sophomore but I'll be 21 by the time rush comes by because I took a while trying to figure out what major I wanted. Anyways I did some research and all I really know is that Greek life at this campus is not as big of a deal as it is at other schools because it is smaller. I wanted to know if you think I'm too old to join a sorority. I really want to go through recruitment but it would suck not to get a bid just because of my age. Any thoughts? Advice?
