The New Hampshire Campground Owners Association says advance reservations are strong and is predicting a 10% increase in business this summer, Associated Press reported.

Executive Director Gregg Pittman said in a statement Thursday (May 27) that the positive economic outlook and stable gas prices are among the factors in the upbeat forecast, on the heels of good weather so far this spring. May rains hampered business last year.

The organization says there are about 230 campgrounds in New Hampshire, most of which are privately owned.
