I don't think there is anything to worry about. This club is staying in Lethbridge.
If the Board ever receives a formal offer from someone wanting to buy the franchise, it is still their decision whether or not they choose to accept the offer to sell the franchise. A potential offer would easily get shut down if it was from either an out-of-town buyer or from someone who had plans to move it elsewhere.
Keep in mind that the Board members don't "own" the franchise outright. It isn't like each Board member would gain $500 000 in a potential sale. It makes no difference to their own personal financial situation whether they had to accept a $10 million offer from an out-of-town buyer over a $7 million offer from a buyer in Lethbridge.
In fact, I believe in this potential situation, the shareholders as a whole would be given the chance to vote on a potential sale. They are all hockey fans and most are season ticket holders. There is no chance that an unsafe offer would be accepted.
And if I am wrong... the WHL Board of Governors still has veto power over the Canes Board of Governors. No one is admitting to what happened with Chilliwack last year but at least the Governors helped save Tri-City from losing their team a few years ago from those same two morons (Brian Burke and Glen Sather). Here's hoping the League would be on our side!!
