Herein lies the uniqueness of the Hash. A worldwide camaraderie of hashers with no formal structure, getting together for a common purpose.
Hashers frequently describe themselves as 'a drinking club with a running problem', and the social element of hashing is of equal importance to the running. The seriousness of the running and of the drinking varies with each chapter. Some chapters focus on running while other focus on drinking. The length and difficulty of runs varies accordingly between each chapter.
Practices also vary from chapter to chapter, country to country. What follows is true for most chapters.
Several regional directories or international directories have been published with Hash Contact information, although the Internet has become the primary source of hashing information.
Each chapter has its members who pay a subscription. This includes the drinks after the runs and other freebies given occasionally. But generally no membership or reservation is required to join a group and being a guest is welcome, for a fee. Typically all that is needed is to find out the time and location of the start either by emailing a current member, viewing the group website, calling the information phone line if available, or just showing up. Most groups conduct a "chalk talk" where introductions are made and the system of hash marks is explained to new hashers and visiting hashers who may be used to a different system of marking. The exception to this would be special events, such as camp out, pub crawls, etc., that require significant pre-planning of food and beverages, however even then walk-ins are generally welcome.
Chapters usually run weekly, but many run monthly. There are numerous celebration runs to commemorate various events. These could be local to the chapter such as a run with a uniques number, 111 or 1000 or such and festive runs. The special events could be a national hash, Nash Hash, or regional hash events.
Every two years, an international meet is organised, referred to as the InterHash. Members at one will vote for the next location and so on. Attendance recently has been about 5000.
The traditional symbol of the hash is the outline of the foot, with often the words "On-On" written upon it.
