I added the "news release" tag because this article is light on substance and seems very promotional. Could some sources be added to show that these actually exist and are notable? Movingboxes (talk) 03:25, 7 July 2008 (UTC)
You must have seen an earlier or developmental version of the article. The current article cites several references of long term series of such events. There is also a link to a website that lists a lot of of additional such events. To me, there is no commercial interest involved in this article. —Preceding unsigned comment added by 18.104.22.168 (talk • contribs) 21:17, September 7, 2008
