SoCal parks as a whole don't have good records in maintaining their woodies. I mean, Ghostrider at Knott's was probably my favorite coaster EVER when it first opened. Now, I can't even ride it it's so rough.
Is it the dry climate in any way? I seriously don't know how big a role that plays, or how much it can be combated. But I've heard a lot of similar comments about Ghostrider (only rode it once myself). On the other hand, the Giant Dipper in Santa Cruz, with much higher humidity, it simply incredible after 80+ years. Of course, they must have to do something to fight the corrosive effect of salt in the air. Grizzly at CGA (formerly PGA, formerly MGA) was awful from the beginning, but it hasn't gotten any worse over time. Roar isn't all that old, yet, and Vallejo gets regular fog and is close to the Bay; it's doing fine. I guess if I was truly hardcore, I'd be in ACE and know this stuff.
Yea i got to Santa Cruz BW, SFDK, and CGA several time a year. Giant Dipper is 1 of the funniest rides ever and looks better than ever and fun every ride. Roar is very fun got a little bumpy through the years but still really smooth at mostpart and really twisty. Grizzle shockenly wasnt bumpy at all last week i went. I noticed they took out the 2 cars in the back which probably made the ride lighter & Grizzle has the nicest scenery. Those are 3 woodies that are taken care of
