Transportation to Devil's Tower, WY

Greetings - Though perhaps a far stretch, my partner and I are looking for a ride to, or even in the direction of, Devil's Tower on March 22nd, from Spokane. If you happen to be heading that way, and have two seats open, we would be most thankful, and certainly willing to contribute to gas. We may end up hitching out that way regardless; I thought it was worth a shot to post here first, should there be any others with a similar plan, and a car.
