I don't know man. I know somebody who recently made Daddy Pig their 500th roller coaster and it's made me think that I've been going about this all wrong. Stuff of legends right there.Yeah I would. Merely a personal preference here, but a fab milestone coaster (and of course the goony photo that goes with it) is way cooler than a larger cred count.
For example, my 200th coaster could've been the kiddy cred at Liseberg.... or Wildfire!
I mean, that's a no brainer, surely?
