We can start a list and have the person and the amount of guest something like:
Evilc (1) - Non-Z
Cygnuxs1 (1) - Z
So name, number of people you are bringing and if you plan on driving your Z.
After this, next step is to plan on location and set it up for maybe 3 weekends from now? I dunno, you older folks always have something to do
Wait I guess everyone planning on bringing the Z will only have 1 guest! LoL
