Lawrence and the nation are ready to celebrate the last major holiday weekend of the summer, and a record 34.1 million people are expected to take advantage of it and travel more than 50 miles, according to Kansas AAA.

Improved consumer confidence, widespread discount airfares and increased confidence in travel security are key factors spurring the travel interest, association officials said.

At midweek motorists were finding the average price for regular gasoline in the Lawrence area at $1.84 and a state average of $1.83, association surveys found. Nationally, the average was $1.86. That could increase slightly over the weekend, officials said.

Clinton Lake State Park is preparing for the usual crowd of about 3,000 people for the weekend, manager Jerry Schecher said.

“We’re just trying to make sure all the facilities are ready,” Schecher said. “You never know what is going to happen, especially when it comes to the weather.”

The National Weather Service in Topeka was predicting a 30 percent chance of thunderstorms Saturday night through Monday with high temperatures in the mid- to upper 80s.
