The Sheikra Rollercoaster is one fo the best in the world, with two 90 degrees falls. Located in the Busch Gardens, it is the perfect place to have fun!

I would love to ride this rollercoaster because a friend of mine, Caio Menini, said it was a great rollercoaster with awsome falls and even a water path part! It must be a really awsome place and would definately bring some adrenaline to my day.
