WYOMING, Minn. — April 20 has garnered the reputation for being a day to celebrate marijuana, because of its 4/20 date.

There are various rumors about how 4/20 became representative of smoking pot, but the one that seems to be the most likely is about a group of high schoolers in the 1970s that would use 420 as a secret code and meet up at 4:20 to smoke.

In any case, one police department in Wyoming, MN is notorious for having some fun on this day.

The department says undercover 4/20 day operations are in place with incognito traps set up throughout the city.

A trail of snacks leading to a trap under the watchful eye of an officer with binoculars is sure to catch anyone wandering around with the munchies.

This year's stakeout is a follow-up to last year's trap that also went viral.

The department did add on a serious note, "if you or a loved one are having issues with substance abuse please feel free to contact us so we can point you in the right direction to get some help. That does NOT mean jail time." They also posted a list of resources.
