I can't reiterate this enough, and apologies to Arty and Worm when I say this because they live there.
But Edmonton is one of the worst places in North America to live, point blank period. Worst winters in the league by a fair margin, one of the smallest cities with one of the smallest metro areas, but unlike a bunch of other questionable ass cities with teams in the league, Edmonton has no affluent suburbs of note to escape to if that's your bag.
No one should be surprised if he decides to pull the pin and go elsewhere.
