In many ways, the Celts have had an effect on my career decisions.
Some time ago, I'd gotten a great job offer from Houston and I almost took it. For me, I'd have no issues living there... enjoying the plethora of fine dining est, reasonable & friendly people, warm winters, and watching the Rockets (or any of the neighboring cities' teams, Spurs/Mavs) play. And the prices of homes were really on par w/ my budget. For swimming in the ocean, however, one needed to make a ~2 hour trek to Corpus Cristi but that's ok.
All and all, I didn't go and stuck it out w/ my local job and sometimes, I have lingering thoughts on if that other job might have been a better choice.
Now, on the flip side, a similar type of job opportunity arose in Southern Cal but I had no problems turning them down for the combination of taxes, road traffic, idiot residents, and the Lakers were a turn off from the get-go. The difference, however, was that the office was friendly and perhaps a bit less cut throat then some of our Boston locals and transplants.
All and all, the issue was clear... the Rockets, Spurs, etc, are the good guys of the league, the Celt's sun belt cousins, whereas the Lakers (& sometimes the Knicks, but a little less so) represent the anti-thesis of Celtics nation.
