Wifi and a water proof keyboard, nice sound system. If money were no object a dishwasher...
haha - a dishwasher might be pushing it. wifi will be all over the house, so no issue there - will just keep the laptop away from any water sources (or 'sampling' friends). but speakers in the brewhouse is one thing I'd forgot, good idea!
BTW, a nice alley for cornhole will be right outside the door.
