When I went to PT school I was in the second graduating class. We were still in the process of establishing clinical sites and we had to be bold. Just pick a place and call them. tell them what you are looking for, when you want to come and ask if they do PT internships. If you happen to be doing it at the right time they might want the extra bodies. Your school needs to be ready with contracts for new sites.
You could also do some investigating and find out what clinic does the rehab for the team you are looking for when they are on the road. I worked at a clinic in KC who did the rehab for the Royals when they were out of town.
