Yup, a lot of pharmacy schools nowadays almost HAVE TO have students do rotations in other states for several reasons. Usually it is a bad thing for the student (longer commute, got to wake up earlier, or move for 1-2 months for no reason), but I guess a good thing in your case?
Rotation sites depends on several factors. The most important one however is who is partnered with your school. I know a few pharmacy schools where rotation sites were out of state because the director of pharmacy in that hospital, or pic in that ambulatory site left, or the pharmay was too busy to handle increased students. Finding rotation sites (believe it or not) can actually be quite hard for the school. Who knew?
