[EBB Sightings] Best time to visit Sunol Regional Wilderness?

All,

As people respond to Michael's question, I wonder if everyone could suggest the best way of birding the area. It seems like there are lots of trails and hearing everyones favorite routes would be helpful. I'm planning a trip to the area soon and need a bit of guidance.

Thanks in advance,
Matthew Dodder
