The Guild is an un-official "umbrella" group of stand-alone homebrew clubs throughout Maryland. I am not on the local committee, but the AHA asked if Guild member clubs would consider pouring on Thursday during the Kickoff party, because they ran out of available space for Club Night. We were each given the option to switch nights.
I believe that all of the Guild member clubs except us (Midnight Homebrewers' League) are pouring on Thursday instead of Friday. We opted to stay with Friday, because a few of our members who have beers being served at Club Night, will not be in attendance on Thursday.
