The first 200 cars to show up at Wildlife Safari Park near Ashland each day this weekend will get in for free.
Omaha's Henry Doorly Zoo and Aquarium announced the deal to celebrate the park's last open weekend of the season. It applies to the first 200 cars Saturday, then again Sunday.
The park is open 9 a.m. to 4 p.m. both days, then closes for the winter.
Regular admission prices are $5.50 for children ages 3-11, $7.50 for adults and children 12-plus, and $6.50 for seniors.
Wildlife Safari Park offers 4 miles of drive-through North American wildlife viewing, including more than 60 American elk, American white pelicans and a prairie dog town, with the chance to also view deer, Sandhill cranes, trumpeter swans and bison.
There are also walking trails midway through the park, where people can view six grey wolves and two American black bears, plus visit a "Hands-on Corral" with pygmy goats and chickens, and an eagle aviary with four bald eagles.
The park is located off Interstate 80 Exit 426 between Lincoln and Omaha, near Strategic Air and Space Museum and Mahoney State Park.
