I don't like them...
as a kid I was at an amusement park with a group...I pigged out of hotdogs, cotton candy and every other bit of junk food I could cram in my body and got on a Ferris wheel. It was a fast one and with every spin I got worse and worse, that green about the gills look trying to hold down that bad assortment in my stomach. I didn't get sick on the ride itself, but I think I burned the nearby bushes to the ground with the foul mess that came up after I got off the ride.
I have been on a few since, with my kids, with my grandkids, but I don't enjoy them.
