My first introduction to Alpha came in the form of a movie entitled....School Daze.(suprise, suprise)
Hell, I started researching the fraternity after viewing the movie again in highschool.
I was
very active in my undergrad years and so were the Alphas on my campus. They had their hands in everything student and community oriented. We worked together in a number of orgs on campus. From student mentoring programs to clean up Carbondale (college town) IMO, out of all the orgs on campus, they were the most active. I did myself a favor and researched all orgs before I made my final decision. Although I felt that every org had a fascinating history, national, and local programs, Alpha was consistent in service, not just during their week. The personalties of members also factored into my decision as well.
ETA: There was an Alpha who had a lot of influence on me as a child (didn't know he was one at the time).
