[Q]: Wow, the PC police from California have finally made it to Alaska.  I never figured they would. Must have been this last mild winter that allowed em to make it up here. I wonder whose coming next?  

You're either going to have a dogsled race to Nome by the fastet mushers in the world or you're going to have something less. 

So you banned a guy for DV, what's next?   Driving violations?   How about shoplifting when the musher was a kid?   How about unpopular speech?  Will I be banned from entering if I display a Christian bumper sticker on my truck?  Will we have to submit to a criminal backround check and submit a blood sample in the future?

Some advice...let the courts punnish law breakers, you guys focus on running a dogsled race to Nome.
