It was a bit of deja vu today at Dorney Park near Allentown.

Twenty-one thrill-seekers hopped on a roller coaster over and over again, all in the name of charity.

I love how it drops you, said Jacob Geist.

It's one of those rides you can ride over and over again, said Tim Dannery.

And that's exactly what the roller coaster enthusiasts did on Dorney Park's Steel Force roller coaster from 10 until 5 today.

We're hoping we can stay on all night, said Toni Petillo.

The coaster lovers are on a mission to raise money for terminally ill kids.

Riders get sponsors. The money they raise goes to "Give Kids The World," an Orlando-based charity giving terminally ill kids and their families a one week paid vacation, which includes passes to amusement parks across the country.

Feels good because they're sick and I can help them go on vacation, said Geist, 13, who raised $65.

Dannery raised $300.

Gives me a chance to do something I like and help kids along the way, said Dannery.

But Carrie Myers led the group with almost $1,400 raised.

Excellent opportunity for kids to go on vacation and be free from doctors and medicine, said Myers. It just lets them be kids for awhile.

Online group coaster buzz organized the charity, which extends to 11 Cedar Fair parks across the country, including Dorney.

The enthusiasts expect to raise $20,000 by riding the coasters.

When you have the opportunity to make those last years they have be joyous, especially to live life to the fullest every day and that is what we can help these kids do, said Charles Hutchison.
