met some frats at the tables today

I'm an incoming freshman and would like to give my thoughts on the frats that I talked to at the tables today. I was first approached by FIJI and they seemed pretty cool but nerdy and I knew that house wasn't for me. Then, I talked to Pi Kappa Phi and they seemed chill and were easy to talk to. However, when I asked them about philanthropy, all they mentioned was riding bikes to raise money? Next I went to Kappa Sigma and they seemed pretty rowdy. I talked to a dude that was someone calm and basically they said that they like to have a big brotherhood, which I thought was awesome. Then I saw Sigma Chi's huge letters and went to there table. They talked to me about their alumni relations and how their house was close to campus. They also mentioned that I had an opportunity to mold the chapter because they were somewhat new on campus. Finally, I stopped by Theta Chi's table. They said that they like to keep somewhat a low profile but they are very big on philanthropy and mentioned Theta games. Just some of my thoughts of how the first day of tabling went
