Grad school too late to go greek?

[outsider]

Hey guys. I'm heading back to school this fall never having had the chance to join up as an undergrad. I transferred from a non-greek campus to a greek-saturated campus after my sophmore year, and figured I didn't have the time as a junior to give fraternity the committment it deserves.

After graduation, I regretted not having had the experience. My father and grandfathers were brothers, and they regarded the experience as one of the most enjoyable in their lives. I'm heading into a new school, new program, and new town, and I figure this is the kind of thing a social organization is made to help with. Thing is, I'm five years out of school, and I don't want to be trying to fit myself into an organization that doesn't want older students.

What's the deal? Are grads welcome (seriously)? Is brotherhood a dangerous thing to try and balance with a grad courseload? Or, is there a chance I haven't missed the last opportunity?

b.t.w. I'm not going to be surprised if you all say that greek life is better suited to an undergrad's role. I'd rather know that to be the case if it is. I'm asking because I figure, nothing ventured, nothing gained. Right?

Thanks for your input.
