MVC .NET Create Drop Down List from Model Collection in Strongly Typed view

So I have a view typed with a collection like so:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IList<DTO.OrganizationDTO>>" %>

The OrganizationDTO looks like this:

public OrganizationDTO
{
    int orgID { get; set; }
    string orgName { get; set; }
}

I simply want to create a Drop Down List from the collection of OrganizationDTO's using an HTML helper but for the life of me I cant figure it out! Am I going about this the wrong way?

Should I be using a foreach loop to create the select box?
