I keep a deck in my bag and I have been accused of missing greens on purpose. lol
However, I swear I do not miss them on purpose.
It is a fun game. The last time we played, my buddy, the one who accuses me of cheating actually won. Even though I ended up with 12 cards his hand was better. I think he had 8. It was at a course we play a lot and can read the greens in our sleep. lol
