Closest the pin

Hi All,

 I've set up a round of golf for a mates stag do this weekend. I wanted to set up a closest the pin comp on one hole. What the best way to do this? I guess I need a marker, but should every player mark it? & what marker to use. I guess a post it note would be no good!

 Cheers

 Paul

I'm still waiting for my society to have a nearest the pond competition I might win that. 

Not if you invite Chris Perry.
