Couple things:
@Saris- in the initial meeting it was agreed on for Antietam, pickets would be best for even and no bias. Then the 3 maps where selected by the officers in the 2nd meeting it was supposed to be one that favored each side and then one that was as neutral as possible.
As far as pubbies, if you bring you allotted 40 players, then no pubbies issues as map will be capped at 80.
These are all moot points as there has been zero replies from people signing up for this, so its probably going to die out. Not sure why, as before we started setting this up there was a lot of interest and oddly now there is none...
