Playing second shot from a tee box
Bearing in mind that the 'Teeing Area' is defined as the area created by a line between the markers and two club lengths back from that line. Nothing in the definition about it being mown or prepared (though obviously it always is) as the whole of the piece of ground (often raised) in which the 'teeing area' is located is likely to be mown and prepared. [Edit] Oops - repetition though not quite so precise
Mind you makes it worthwhile thinking about teeing back from the front boundary of the teeing area - just in case you almost miss the ball and it trickles off the tee peg. If you tee up on the front boundary of the teeing area you lose the chance of re-teeing it for your second
