Drawing is good for you.
Drawing trains your fine motor skills, stimulates concentration, and reduces stress.
In a world where we are deluged with stimuli, drawing causes us to sit still, observe, and admire the beautiful world and the people which surround us.
The drinks are symbolic for the social aspect of DnD. Drinking is not necessary at all. Lots of events happen in places where it is not even allowed to drink. So we Dance and Draw, Cake and Draw, Kink and Draw or Swing and Draw. We tried to change the name, but Drink & Draw just stuck. It works.. like Rock & Roll :)
