Roller coasters have been my main hobby for the last 20 years. I just got back from a trip to Cedar Point, Kennywood, Waldameer Park, and Conneaut Lake Park this past weekend. Although I’m most into roller coasters, the parks I like most are visiting both Disney locations in the US (WDW and DL). Outside of Disney I highly recommend Cedar Point for their wide selection of roller coasters, and places like Busch Gardens Williamsburg, Silver Dollar City and Dollywood for the overall package (Rides, Food, Shows, Scenery).
Here are some of my favorite roller coasters....

Steel Vengeance- Cedar Point
Fury 325- Carowinds
Superman- Six Flags New England
