Zip (roller coaster)

Zip or Zipp[1] was a steel-framed wooden roller coaster which operated at Oaks Amusement Park in Portland, Oregon.

The coaster was also built on a wooden deck to protect it from Willamette River flooding.

Robert Cartmell, in his book The Incredible Scream Machine: A History of the Roller Coaster, described the stunned reaction of attendees at an American Coaster Enthusiasts meeting when photographic slides of the Zip were first shown.

"[It was] as if some primeval nightmare had been projected on the screen" Cartmell wrote, and called the coaster "a ride bordering on the macabre".

[4] It has also been suggested that the shorter trains may have created an even rougher experience than was typical for a Traver Cyclone.
