What can I do to keep up with my Spanish over summer?

I just graduated high school and I am pretty decent with my Spanish. I am starting college next year where I will be majoring in Spanish. I am looking for something to do over summer that will help me keep up with my Spanish, because not practicing it for awhile makes me loose it. I was looking for some kind of internship online, but I couldn't find anything. I really want to do something in person. If you have any ideas your help would be greatly appreciated. I live in the Milwaukee Wisconsin area, if that helps.
