Find out if other events are going on in the area. When events occur at the same time, there is a chance that crowds will be affected. A competing event can have a positive or negative effect. Competition can draw participants away from an event or attract participants who otherwise would not have attended. Check on the sponsorship.
Sponsorship makes a difference in the kind of crowd.
For example, fairs sponsored by craft associations draw people who enjoy crafts. Fairs sponsored by charities may attract people who are not particularly interested in crafts, but come for other reasons. As a result, the number of buyers might be limited. Find out whether a fair is juried . This means that a panel of judges is convened to evaluate each entrepreneur's products and decide who should be invited to participate in the show.
