If you haven't already been given someinformation, I obtained this for you from the USfirst.org site.
The Las Vegas Regional will be March 31-Apr 2, 2005 at the Thomas & Mack Arena at UNLV. You may consider volunteering for this since it's in your town and all.
If you'd prefer to work with a team, the following teams are listed in the Las Vegas area.
987-990 are all teams in the Las Vegas area.
1703 is a rookie team in Las Vegas as well.
Of those teams, 988, 989, and 1703 seem to be tied to UNLV (I might assume you go there or somewhere close?).
If you'd like to follow up on this information, the
site is here. Good luck!
