I think a lot of companies put their social networking/marketing in the hands of young men and women because they are perceived as being good at it. In this case, I would like to believe that it's a simple mistake, an uninformed 20 something that doesn't know who the HSUS is, heard that the donations were going to the Humane Society and then tagged the HSUS instead of the other place. I can't believe the brass at Muck would be dumb enough to do something like this, I'm pretty sure they're aware of who they're selling boots to.
Muck boots are awesome, as long as they handle this right I won't stop buying them.
