Ross designed a shared tee at Country Club of Columbus (GA) for #1 and #10. It is also the practice putting green too. So, you roll your last practice putts and then step right to the tee with out leaving the area. Someone mentioned noise/distraction. It is a consideration, but tends to a great first tee experience in competition.
Great club by the way. Ross course, great membership, no tee times and run by a great PGA Pro, Brian Stubbs.
