RIVERVIEW definitly. I also have read Riverview: Gone but not forgotten. That placed looked so great. Aladin's palace, 11 coasters, including the Bobs, Ribbions (virgina reel) and Flash (the strangest cars i've ever seen). Then there is Par-o-chutes and the great collection of flat rides they had there. The amazing amount of people who have replied riverview just strengthens my argument that SFGAm should reconstruct the Bobs.
If you want more history on riverview if you live in chicago i recomend you go down to the historical society (right nelson?) and check out some of the information there, they have a lot. If you don't just check out the book i mentioned above.
