The MN Wild sometimes practices at one of my usual rinks. We can tell when they are there....the whole parking lot is full of expensive cars; also the press is there, so it's hard to find a parking space.
The bonus is that the whole rink staff is watching them, so you might get to skate for free (no one minding the store!). It is kinda fun to see them go through their drills. They are amazing skaters.
