Saturday is 4/20 – which is sure to put a smile on the face of any weed smokers out there.

This year could be the best 4/20 ever, as thousands of people are heading to Colorado and Washington this weekend, including people from out of state who are on packaged tours.

One of these tours is called “My 420 Tours.” Located in Denver, it gives traveling pot users everything but the drug, with prices starting at $499. Tourists can add extra days of touring medical marijuana dispensaries, commercial growing operations, or taking a cannabis cooking class.
