Local police will be out in force for another "No Refusal" weekend -- this time looking for drunk drivers leaving the Renaissance Festival.

Montgomery County prosecutor Warren Diepraam says they typically see a 20 to 30 percent increase in DWI numbers during Renfest.

“Typically there are 30,000 people a day go up there on Saturday and Sunday, most of them celebrate responsibly, but unfortunately too large of a number of people do over indulge in alcohol, and that's what we're trying to prevent,” Diepraam tells KTRH News.

Even more activity is expected this weekend.

“We've got the Renaissance Festival, but we've also got Halloween weekend,” says Diepraam.  “There are going to be a lot of parties this Saturday involving alcohol and people celebrating Halloween.”

State law allows police to draw blood from DWI suspects if the driver refuses a breath test.  Police will focus their efforts near Magnolia, or Highway 249 in particular.

“Well be ready with prosecutors, judges, nurses and search warrants to make sure we get that scientific sample,” says Diepraam.

This weekend's No Refusal period runs from 9 pm Saturday until 4 am Sunday.
