I was living in Nebraska in the 70s, and it was a tradition that the Highway Patrol would wait basically on the Colorado state line and stop cars with Nebraska plates coming back from Colorado and search for Coors beer on board. They didn't sell it in Nebraska for some reason then, so it was illegal (Smokey and the Bandit-type of thing).
The news would routinely have video of bulldozers crushing Coors cans. After college football games there you'd always see this story, especially since at that time the Cornhuskers could win a game and would always win in Boulder.
When we'd manage to return from a ski trip with Coors (hidden) in the trunk it was like we'd escaped from the prison in Midnight Express.
You'd think with the Coors people being so Right Wing that they'd figure out how to make the system work and sell their beer everywhere legally. Then again, taxes bad, etc.
