The last time I went was to Wet & Wild on Orlando with my cousin when we were like 15. It was fun until she hooked up with a lifeguard and went out to his car with him so he could get a change of clothes to hang out when his shift ended while I grabbed a bite and used a phone (remember payphones?). That fucking asshole raped her in his car, pushed her out and took off.
They just weren't fun anymore after that experience.
