It could be another challenging year for Michigan's tourism industry.
Tourism in the state is expected to grow by about 2 percent this year, according to a forecast from Michigan State University's Tourism Center.
The state's sluggish economy and gas prices are among the factors restricting the industry's growth to a modest pace.
The tourism industry managed to increase sales by a little more than 3 percent in 2006.
Sales likely would have been stronger were it not for an exceptionally rainy fall color season.
In 2007, the number of travelers in Michigan is expected to increase just 1 percent to 2 percent compared to last year.
Travelers' spending is expected to increase by about 4 percent to 5 percent.
