Warning people, "...about 60 motorists during 4-hour," periods seems excessive. Even if there was a safety operation going on at the time.

I'd think we'd see more than 60 people driving into the Taco Bell during that time. Perhaps the police were warning us about 60 SPECIFIC people? That would make more sense. The RG should have told us which 60 motorists we were being warned about. 

Maybe they're 60 "guests" from the hospital in Junction City? Out on 4 hour passes?
