Dave - We really like Whitehall! We've anchored just inside Mill Creek and been quite happy (I'm a sucker for having a view of the Bay Bridge from our anchorage at night.) The entrance is tricky but very well marked. Nice breezes inside but calm, we anchored in 8 ft. You can dinghy up to Cantler's just to say you did, and I think Jeff H. lives off Martin's Cove.
If you want shelter, OTOH, friends anchored in Ridout Creek off Whitehall Cr for Isabel and claimed they never saw more than about 35 kts.
