Free Beer on Beer Day?

I don't think this was what Mayor Tom Barrett meant by "Beer Day":

From Channel 4's website:

MOUNT PLEASANT - Mount Pleasant police need your help to find a lot of stolen beer. Someone ripped off a trailer with 1,600 cases of Miller Beer from a trucking company. The beer is worth $24,000. Police say someone stole a tractor from Illinois and hitched it up to the trailer of beer.
