I know at coaster (RnRC) we've had a lot of 101's recently. Told a buddie of mine "Watch. First five minutes that Im back at Coaster, we'll go 101" (I had been at Fantasmic a lot at that time.
Sure enough, five minutes after I walk into Launch Base, we go 101 because a woman managed to drop her purse into the pit at load BETWEEN THE CARS. (Dont ask).
But the biggest thing we've had 101s because of is...well Im not going to say because you would get worried about being on it (Seriously!). It's nothing major, and it's even being worked on at this minute but still....
Another time a few weeks ago, a fire alarm went off in the gravity building for NO REASON WHAT SO EVER. It just malfunctioned and went off. Reedy Creek was called out, building evacuated, 101, then 102 like two minutes later.
