I'm almost sold on attending USF but I would like some opinions please. I'm a non traditional student due to spending my 20's in the Army, and my major concern is not being able to relate to too many of the younger students. Is there a lot of older students?
What about race relations? I've heard some bad things about USF and race. As I've said I come from a Army background [I believe the military is the most intergrated institution in America] and I would prefer to not have to deal with large populations of ignorance.
I thought I'd would go straight to the source for answers. 
I am an Afican American male, who received my Bachelor's (2001) and Master's Degree (2006) from USF. I also work at USF and have worked here for 7 years. There were a fair number of older students in most of my classes, but I wouldn't worry about relating to the younger students. For the most part you are going to run into a lot of people who are in your same situation you are especially with MacDill Air Force Base being here in town. You are going to have your share of people you will and won't get along with, but I can say my experiences were mostly positive in that regard.
When it comes to race relations, I never really had any big problems dealing with race during my time at USF. Of course I ran into some ignorant people (they are allowed to attend school as well) from time to time who may have come from an area that didn't have many people of other cultures, so they had their opinions formed by TV or public stereotypes. You can't really do much with those people, but they are not the majority here at all. You are probably referring to the situation with the woman's basketball coach several years ago, that got a lot of attention, but I wouldn't say that was the overall feeling of the USF community. Racism exists and schools and organizations don't want to deal with it if they can help it, and I think where people were outraged was due to the fact that an investigation was conducted before this incident became public to gauge race relations at the university and the investigator allegedly found a problem with the women's basketball team and the administration allegedly didn't want to read it. I don't know how true it is, but the situation was resolved with the coach being dismissed.
I lived in Tallahassee before I came to USF, and this area is light years ahead of Tallahassee when it comes to race relations. You will enjoy your time here if you come.
