In Pittsburgh, hailing a cab was tantamount to putting in a bid to host the Olympics. It seemed like you had to wait years for one to show up! So, I was an early cheerleader for the new mousetrap for hailing a cab - Uber. So easy! So prompt! So intriguing - peering at that car icon on my phone, starting up in Oakland weaving its way down Fifth Ave. across Grant St., turning on 7th St., eventually picking me up at QuatriniRafferty's downtown Pittsburgh office, at 941 Penn Ave., to take me to the airport.
