Hit every roller coaster at 6 Flags, but the best ride was easily Xcalibur. I need to ride it on a cloudier day or at twilight, so that the sun does not force me to close my eyes to the unrestrainedly shifting horizon.

The rest, best to worst:

Batman- Excellent all-around.
Ninja- Very nice spirals.
Mr. Freeze- Short but thematically intense.
Screamin’ Eagle- Nothing too memorable, but some good drops.
The Boss- Too woodenly rickety.
River King Mine Train- Too tame, especially having the misfortune of being ridden following Batman.
