I got my sister to go on River Rocker because all the coasters were closed. Then as were are on the ride, it started to down pour and there was lighting right above the park. You could tell because you would see a HUGE bolt stretch across the park and instantly you would hear thunder. My sister was now really freaked out and I told her "yeah, they know what there doing". Then the op was like "River Rocker is now a water ride" as we were getting soaked. Then when the ride was over, someone came up to the Op and yelled at him, I think it was for not stopping the ride or something. After that, we just rode Chabasco and played DDR till the storm lifted. Even though the coasters werent open, we rode River Rocker and Triple Play till the park closed.
Heres a Pic from River Rocker during the storm...
Its sideways and taken with my phone but you can see how have of the park was bright and sunny, and this huge storm came rolling in. Look at Raging Bull glow.
