Sorry you didn't have a fun day. I had a blast yesterday. I was there from open til close, and racked up 36 rides on Diamondback (thanks to the single rider line). During the "rain" downtime, just hung out with friends I don't get to see often, and waited for things to open up. Diamondback reopened around 7pm, and it was just flying the rest of the night after the rain.
FYI, it wasn't just the rain that closed rides, as they do run some rides in the rain, it was due to lightning in the area that closed everything down for the extended time. It was still lightly raining when Diamondback reopened, and all I can say is WOW! What a ride! I went yesterday because I wasn't going to make it to the RW even this weekend due to prior committments.
