Hi, I'm Emi from Vallejo, California, home of Six Flags Discovery Kingdom. Our Medusa is better than the one in New Jersey. I have ridden over 600 roller coasters but I don't count them because this is my husband's hobby. He's ridden more than 640. I like TPR because they put on awesome events at Magic Mountain and their DVDs are really good. We are using them for training our twin girls so they won't be too chicken to ride roller coasters when they get old enough.
