Are my hopes for joining a fraternity over?

[piotrkol1]

I'm a sophmore at the University of Arizona in Tucson and I decided to rush this week to try to join a fraternity. There's like 16 of them here and since I didn't really know much about them, I just randomly kinda picked to visit 7 of them which were having open houses in the evening.

Monday: Visited Phi Delta Theta, Sigma Chi, and Delta Tau Delta in the evening. I was somewhat rushed because I had an intramural basketball game that night so I didn't get to spend a whole lot of time at each one.

Tuesday: Visited Tau Kappa Epsilon, Sigma Alpha Epsilon, PIKE, and Delta Chi. Phi Delta Theta had called and invited me back that night (even though it was still an open event) but I decided to take the time and visit those four new places instead.

Wednesday: Delta Tau Delta called me and said I could come to their invite-only event. I got there kinda late since I had class in the evening, but I was still there for like an hour and a half and I met/talked to some of the guys there.

TKE and Phi Delta Theta were my other two favorites and they still had open events on Wednesday, but since I had class late I only had enough time to go to Delta Tau Delta. Now its Thursday and I didn't get invited back to any of the three tonight. Bids aren't given out until Saturday, but seeing as how its doubtful that I'll get invited to tomorrow's invite-only events it looks like I wasn't even close to getting a bid from any of them. I'm pretty disappointed because I wanted to join, and since I'll be a Junior in the fall I'm not sure if its worth trying again.
