Oh dear, how gutting! Thankfully, the USA has a wide array of options for milestones; Maxx Force or Steel Curtain would certainly make good ones if you visit SFGAm or Kennywood as you said above!It's rather frustrating because I'm just going to miss it. As a result, I'm looking to get 300 at whatever new American/Canadian park I can get to this year. Six Flags Great America looks most likely, but I could also find my way Kennywood beforehand. Prices for flights from NY to Pittsburgh are rather attractive. However, there's also the temptation of Toronto and Canada's Wonderland with its legal weed and alcohol at 18. So many options!!
