Greetings from Napa! This weekend, I'm headed to San Francisco for a long weekend getaway in wine country. The forecast is lookin' fine, so I'm anticipating mornings sunning by the pool, afternoons sampling Napa's finest vino, and topping off the day with dining al fresco. Ahh, yes, spring is here! Whatever you're up to this weekend, I hope work will be far from your mind. If you could use a little (almost) weekend entertainment, check out this week's medical news link pack.
