IMO, yup PGA has done enough to get the thrillseekers attention. they're obviously a family park.
Quit ya cryin' & whining!! You have a decent coaster collection - Stealth, Invertigo, Vortex, Demon, Grizzly, Greazed Lightning and more.
My home park has just the Demon (1988 Vekoma Boomerang), Bush Beast (1985 KEC clone of your Grizzly - ouch!) and the Beastie (1985 KEC junior woodie)!!
You yanks are spoilt rotten!!! :)
Don't forget PGA has a height limit of about 175ft(Am not 100% sure about this), therefore a Hyper or Giga won't happen.
