Cops in the Cowboy State have an eclipse weekend warning for Colorado tourists: don't bring your weed to Wyoming.

Officials estimate the Wyoming's population could double by Monday. While tourists will be visiting from all over the world, the majority of them will come from Colorado, where recreational marijuana is legal.

Cheyenne Police only issued 8 citations for marijuana possession during Cheyenne Frontier Days, which also draws a large Colorado contigent.

This weekend, some of those greenies will come on vacation and leave on probation.
