+1, intercept...somewhere(Monterey and Acadia?). Cayugayell is really convenient for me and it looks like your path goes near there, so I'd like to pick a point nearby. I think San Jose goes over Lyell, then just after that you can exit San Jose to Monterey. The intersection of Monterey and Acadia is a block past the Glen Park BART and the confusing mess of Bosworth/San Jose/280/Monterey. Does that work?
Glen Park Bart is the other place that jumps out as a possible intercept, but I'm not sure if you're actually going past it.
If yesterday's skyline is any indication, 6:45 is when you'll be rolling through.
