Reno Police estimate there were about 10,000 people participating in the event. Volunteers aged 18 to 20 visited 51 area businesses as part of the Regional Street Enforcement Team alcohol sting and those volunteers were served alcohol at Wild River Grille on S.

Arlington Ave. Reno police say there were 19 misdemeanor arrests, three felony arrests and one person taken into civil protective custody.
