I agree it is an excellent guide to roads in California. What's great about it is the pictures, which let you see what you're getting into (onto). If you are coming from out of state to ride here this guide lets you pick the best roads and maximize your riding time. There are plenty of ordinary roads in the same area as the great roads and you could easily miss them. So knowing ahead of time that you need to "turn left here", for example is well worth knowing.
I live off a road this guy hypes as "The Holy Grail of California's Motorcycle Roads". Thanks to the publicity it's become unrideable... posted 30 mph speed limit, miles of double yellow lines and worked heavily by the CHP.
If you ever ride Skaggs Springs Road, don't even think about speeding or passing on a double yellow east of the bridge, especially on a weekend.
Too bad motorcycling isn't more like surfing, where if you find a spot you STFU and enjoy it instead of blabbing it on the freaking internet and ruining it.
Thanks for the excellent link kowalke. Although I'v ridden the majority of these roads at one time or another there were still a couple of nice surprises here. If you ever make it to Northern California look me up and I"ll guide you around. I live in Red Bluff which is where Hwy 36 West starts. It may be the best motorcycle road in the US. I also know a few rides that aren't on the pashnit site. VWW
