LEWISTON — Mainers are taking the day off to mark Labor Day, the unofficial close of the state’s summer tourism season.

Turnpike traffic was not expected to be quite as heavy this year as last, given the sour economy, gas prices and disruptions caused by Tropical Storm Irene.

More than 100 workers, government officials and political leaders are gathering for the Portland Labor Day Breakfast hosted by the Southern Maine Labor Council, AFL-CIO. A free Labor Day barbecue, sponsored by the Western Maine Labor Council, in Lewiston, is expected to draw more than 400 people.

Meanwhile, the Coast Guard is issuing a safety advisory to boaters and paddlers as they wind up the summer boating season. Coast Guard crews will be conducting safety checks and watching for people boating under the influence.
