NHL Owner Boycott

The NHL owners aren't worried that fans will sour on the game because of a lockout. That's fair because we probably won't.
What we can do is ensure that we don't give money to anything else that these owners own.
Full list is below, arranged by team. A lot of these are difficult and/or impractical.
There are some easy ones though:

Stores: Walmart, Rexall, Pharma Plus, IDA
Restaurants: Real Sports Bar, Denny's, Moxie's, Chop Restaurant, Little Ceasar's
Others: Secret Stadium Sauce, Comcast/NBCSports/Golf Channel, Regal Theatres/United Artists Theatres
Beacon Theatre, Radio City Music Hall
