A North Bay group trying to fill hotel rooms during down periods may get some quick action.  HOST, which stands for Hospitality Organizations Strengthening Tourism, is going after sports tourism events during off peak seasons.  Spokesman Jake Lacourse says since talking to North Bay city council two weeks ago he’s gotten three solid leads.  Two of the leads are winter related and the other is a summer mid-week event.  Over the course of the year North Bay hotels have a 40 percent vacancy which works out to $13.5 million in revenue that could be captured.
