Wichita ? The owners of Joyland Amusement Park have again put the attraction up for sale after several failed attempts to reopen the park.

Longtime owners Margaret and Stan Nelson are trying to sell the Wichita amusement park for at least $2 million.

The theme park has been closed since 2006 as two other groups tried unsuccessfully to take over and keep it going.

The Nelsons – Stan, 85, and Margaret, 75 – now have control of the park again and are trying once more to sell it.

“It has to be cash,” Margaret Nelson said. “This time there is no leasing or holding the note.”

However, she said she and her husband would consider proposals to do something else with the land, such as build a corporate headquarters or another kind of park.

The park opened in 1949, and the Nelsons have run it for more than 30 years.

While closed the past few years, it has become a target for vandals, with more than 20 break-ins reported recently.

Police arrested two men this month after they found spray-painted swastikas and other graffiti on buildings.

“They were really reckless,” Stan Nelson said. “They turned over ticket booths, broke into the office, threw furniture out the windows.”

Joyland’s roller coaster was a product of the Philadelphia Toboggan Co. and is one of the last surviving original wooden coasters designed by Herbert Paul Schmeck. One of the trademark attractions was the park’s Wurlitzer organ with Louie the Clown in front of it.

In the early 1970s, the Nelsons bought the amusement park from the another family, the Ottaways. The Nelsons ran the park until a few years ago, when two different groups made unsuccessful attempts to operate and buy Joyland.

Now the park is overgrown with weeds and the park sits unused.

The Nelsons have sued former operators Robert Barnard and Michael Moodenbaugh. In the lawsuit, the Nelsons listed Louie the Clown as one of the items damaged or taken from the park.

Moodenbaugh has said he and his partner know nothing about the missing clown’s whereabouts.

The Nelsons are looking to collect $450,000 in back rent and damages. Barnard and Moodenbaugh have said that they don’t owe the Nelsons any rent.
