In the international files, there are no records of conventions (probably because of the Depression). Earliest records this office has after the 38th convention are minutes from Ben Springer’s book which start on August 18, 1938 – the time when Hoo-Hoo was reorganized by the Immortals.
During two of the years of World War II, there was no convention held per se. Rather, Hoo-Hoo celebrated September 9th (Hoo-Hoo Day) with each club holding its own meetings, concats, etc. Traveling during those years made it almost impossible to hold a successful convention.
