The map isn't the only out of date thing on the site!
Taken from the Afterburn history section:
Introduced to the park in 1999 at a cost of more than $10 million, Afterburn was the largest investment in park history at that time. Today, as the park’s tallest and fastest rollercoaster, Afterburn ranks as one of the top 30 steel coasters in the world!
On the other hand, I didn't know that it is one of the top 30 steel coasters in the world. I like the new site!
Edit: Whoops, sorry PreferParamount. You already wrote that. Ah well, you didn't say that it was in the top 30, so I'll keep it posted.
