You are not the only person to be bossed by SWMBO and is banned from playing with your toys at home.

We will probably have some of the 6 yard competitors cards shot at RMTC on Thursday nights as well, so it is not a big problem to overcome - thats the reason for having the 6 yard series - its something that anyone can take part in without too much effort.
