Yes I know Diana Dahlgren.... Why?

Was this a trick question or something?

If you want to be apart of the promo team, or anything else for that matter, don't do anything.  You're already apart from it.

Now if you want to be a part of the promo team, do as the other people suggested and contact the agency or marketing company that represents the brand.

well im trying to find how how i can become part of the "team"

Pretty sure that Miss Supercross (Diana for this year) is decided through Feld Sports though I know they've also done some online voting for the position in the past as well.

Monster is the title sponsor for the series but the promo talent for Monster, I believe, comes from a couple different areas. The Connection hires a lot of the local talent that is at the Monster booth out in the pits at each race. Then there are Monster girls that are down on the field during the race and at the awards podium. Those girls I think are more consistent round-to-round as they have specific duties that have to be timed for the show.

Contact The Connection and stay on top of the selection process for next year.

Also keep in mind that a lot of other companies use promo models: Rockstar, Muscle Milk, Red Bull, etc. None of those companies handle casting for local talent for each race in house- WAY too much of a pain in the ass. Your best bet is to contact the marketing department at those companies you would like to represent and see if you can get a number for the agency that handles that for them.

Good idea!
Terra, you could watch C/L for San Diego and LA the next few weeks as those rounds are coming up.
