Yep. I heard on the radio about the parking and shuttle bus plan.
During the cherry blossom season I have more problems with the pedestrians than the cars. From the hump bridge south people wander in the road at random. And don't even try to get across the Memorial Bridge.
IMO Kenwood is usually a better experience. Less crowded, almost entirely locals (instead of tourists) and it's right off the CCT.

Anyone going to the Sakura Matsuri Street Festival? If the family doesn't join me I'll be riding there.
(need my takoyaki fix )
