Honestly I love the basic rides like twister and waltzer, especially since I don't really have any "hardcore" friends so things like this are easy enough to get them on board with and they're just good old fashioned fun. The bigger rides are alright but it's not the same when you have to ride them alone!
There is this one ride though that I've only ever seen at one fair (it pops up annually in our area and this ride is there maybe 25% of the time). Not sure of the technical name for it. It's basically like if you put a twister upside down, replaced the long seats with two-person egg-shaped capsules, and then spin the eggs upside down while everything else rotates too. Great times.
