Roller coasters and other aerial thrill rides. I don't trust that they can be or are properly inspected and maintained. I feel that way about most large and high structures.
I'm too wimpy to go on any ride, especially spinny ones. I puke too easily and it's embarrassing hurling in front of everybody and worrying about puking while the ride it still going and hitting someone with it. Ew.
I can't remember an amusement park ride ever causing me to barf Patch. Usually I just got very scared. I don't know if you've ever been to Disneyland in California but my favorite rides were "It's a Small World", "Pirates of the Caribbean" and "the Haunted Mansion". We haven't been there for many years so I don't know about any other rides that are there now or even if the rides I used to like are still there. Thank you for your reply and Happy Thursday! :)
