If you do not like roller coasters, you are not my friend. For all you thrill seeking afficianados in the know, Six Flags Magic Mountain is paradise on Earth.
Forget all that negativity about how unkempt the park is, and how unruly the crowds may be. The way I see it is that you come here strictly for the adrenaline rush. Leave all the aesthetics and bells and whistles to Bonfante Gardens. This place is for the whiteknucklers only.
Besides, all the teenagers and *supposed* gangbangers (gosh, that word is dropped more than dishes at a Greek party these days) gives the "Mountain" a unique charm. It is located in greater Los Angeles after all. Did you expect anything less?
As for the rides themselves, there isn't much more to say that hasn't been already. Tied for Cedar Point in Ohio for having the most coasters on the planet (17), not to mention the majority of them being record breakers in their respective categories, I'd definitely stick my neck out to say that nothing on the West Coast even comes close. http://www.rcdb.com/pd4.htm
The best thing about it all is that there are plenty of good deals to be found. Look around, and you might notice Coke cans offering discounts, or even some two-for-one deals at the local supermarkets. I am able to use my season pass from Marine World (here, and at any other Six Flags nationwide), which makes it a killer deal.
