“I went to Atlantic City to attend several days’ meeting of a national society of which I was a member. I drank all the scotch they had on the train and bought several quarts on my way to the hotel. This was on Sunday. I got tight that night, stayed sober Monday till after the dinner and then proceeded to get tight again. I drank all I dared in the bar, and then went to my room to finish the job. Tuesday, I started in the morning, getting well organized by noon.

I did not want to disgrace myself so I then checked out. I bought some more liquor on the way to the depot. I had to wait some time for the train. I remember nothing from then on until I woke up at a friend’s house, in a town near home. These good people notified my wife, who sent my newly made friend over to get me. He came and got me home and to bed, gave me a few drinks that night, and one bottle of beer the next morning.

That was June,10, 1935, and that was my last drink. As I write nearly four years have passed.” (Alcoholics Anonymous, pp. 179-180).

Note: Dr. Bob's AA Birthday is actually a couple days later. Founder's Day is celebrated by AA Worldwide as when Bill and Bob first met and began the fearless search for a Higher Power; a process from which many have recovered world wide.
