Sometimes I'm forced to hire a sitter for Jango, my 85-pound golden retriever. Last week I sojourned to San Francisco to deliver an OMMA addressable television lecture -- eleven-year-old son in tow -- and my wife off to Saratoga friends visiting. When I contacted our reliable sitter for the usual -- three walks and an overnight -- she mumbled to me (shoulders slumped, eyes grounded) that there would be a price increase. Her $65 a day all-inclusive rate was mushrooming to $100. "Why?" I asked. "The price of gas," she guzzled.
