I love these stories about cross-state "smuggling."
When I lived up in PROM (People's Republic of Minnesota) fireworks were illegal . . . which meant that fireworks stands just across the St. Croix river in Hudson, WI, did a booming business in the weeks before the 4th of July.
Well, PROM didn't like that, so one day a PROM State Trooper crossed the border and parked in the lot of one of the larger fireworks stores, looking for cars with PROM plates. Asked politely, they refused to leave . . . whereupon all the employees of said store took their cars and blocked in the PROM State Trooper. Much hilarity ensued. Local WI constabulary eventually appeared on the scene and informed said PROM troopers that they weren't tasked with LEO duties in WI, and since they weren't in hot pursuit, they had best leave . . . and were escorted back across the river as a
professional courtesy so they wouldn't get lost.
