I think Ohio was the best ever before SFWoA came into the picture. To the west we're less than 6-7 hours away from SFGAm, IB, and SFStL. To the south, we're less than 5-6 hours away from SFKK, HW, and DW. To the East, we have parks all over the place from KW to BGW to SFGAdv. To the north, MA. We're really the center of the best coasters outside of Cali and Texas. Florida coasters are ok. The IOA and BGT coasters are the only thing notable. And that's only 6 plus RnRC, SM, Kraken, and DBH. 10 great in all couldn't be that high up there, IMO.
Ohio is number 1!!! :)
