this was admittedly quite a while ago, so things have changed a bit since circa 2011-2012, but i was sitting in the lower bowl for a kings/canucks game and there was a couple next to us rooting for the canucks. We started chatting and it turned out that it was cheaper for them to fly from vancouver to LA and buy lower bowl tickets, that to watch a home game.
LA always garners a lot of opposing fans due to the nature of people living in los angeles from all over the world, but ive always hated going to Vancouver and Detroit games the most
