For the third summer in a row, there's been a drop in visitors at Sacajawea State Park in Pasco.
Under the Discover Pass, folks have had to pay $30 to get a yearly pass at Sacajawea.
A one-day visit is $10.
A few years after those fees were introduced, many people still refuse to pay them.
Since the changes went into effect, overall attendance at Sacajawea has dropped nearly a third.
Despite the struggles, lawmakers have no plans to scrap the Discover Pass.
