The one thing I did not like about the finale was how it seemed Ted cut off any and all ties to his time in England. This is not the 1600s, it is pretty easy to get back and forth. I do it several times a month.
I really would have loved to see Ted return home, but have Rebecca give Ted something like 2% ownership of the team, so he would always be a part of the club and it would not have felt like such a hard ending.
I was in college in the 1990s and very few people I know where in fraternities. I had two roommates who were scholarship athletes, and neither of them were in fraternities.
I also think it depends on the college too. At some schools, the fraternities and sororities are big deals, and at others they are not. Based on my very limited experience, they a bigger deal on smaller private schools, and a smaller deal on larger public schools.
