Busch Gardens Williamsburg had built a coaster called Drachenfire at one time. I LOVE coasters, but that was one that I thought might genuinely injure me. I rode it alone, so nobody to compare notes with. I thought maybe it was just me. Next time we were there, it was gone. Evidently, it wasn't just me!
Most recently...Hersheypark built a new coaster called Sky Rush. It has the potential to be the BEST coaster ever. However, there was something seriously wrong with the restraint system. I thought my thighs would snap, no lie. The bar came down in the center of my thigh. The minimal restraint is cool because the airtime is amazing. You can only hold on to your lap bar, and there lies part of the problem. The placement of the bar along with the fact that it TIGHTENED through the course of the ride (due to holding on to it) meant that every time I got air, I would be forced UP while being VERY tightly gripped DOWN mid-thigh. I was seriously afraid my legs would break (trust me, I'm not a whiner about coasters either!) By the end of the ride, my legs were vice gripped. I really hope they fix the restraints on that one because the coaster itself is incredible.
