The Web and Native newsgroups are also sources of information on Pow Wows, and if you don't see anything near you, post the question. Everyone on the network will be happy to give you information. Sometimes Pow Wows are advertised in main stream newspapers, but not often. Pow Wows are very expensive to put on since the grounds are usually rented, insurance is a must, and the Pow Wow officials, head dancers and host drums must be paid. All of this is in addition to the prize money awarded to the winning dancers in each category.
Advertising is viewed as an unnecessary added expense for most.
However, the public relations person at any newspaper should have information on hand for the area of its readership. Wow while on vacation, call the Travel and Tourism Bureau in the State Capitol of each state you'll be passing through, and check the Internet sources mentioned above. Wow during the year. A complete listing of Pow Wows and gatherings in the U.S. and Canada could, and does, fill a book. I highly recommend the annual Pow Wow Calendar as the most complete guidebook to Native events available.
