Madam Dena said that the Valley Inn Lounge at Sheri’s Ranch had a new more efficient air exchange system installed, so the air quality should be acceptable. However, once the bar crowd arrives on Friday and Saturday nights it can still become untenable at times. The Valley Inn Lounge is frequented by the local crowd for food and drinks but they rarely party. During the weekdays between 11 am and 5 pm the air quality is usually very good. The first shift of Ladies aren’t normally in the bar until slightly before lunch.
