I've actually found a way for anyone to get into press events. I'm a receiver of the daily e-mail "Bizarre News"*, and they've just brought out a new thing, called "Bizarre News uncensored".  
It is $30 a year, and for that you get a new newsletter, a mug, and the best part, a press pass. Apparently, according to the editor, this is the real deal, which can get you in to any event which is normally only for media types. Don't know about you, but I think it's $30 well spent. 
 *Bizarre News is an internationally recognized publication, which reaches over 500,000 people, (bizarrenews.com)
