I've been there once. Was a nice set up! As I understand it, they built it to the max downgrade NHRA will allow and directed it so that the prevailing winds are from the rear! Seemed to be a nicely run and well built facility. Took me about 2 hours to get there from here.
Met up with Chris Endres (from GMHTP) and his LS1 Camaro and he had about a 4-5 hour drive from MN... don't think he was disappointed with the setup, and he's seen a lot more tracks than I have! HTH!
