Still think bringing in a small pack from the local zoos to do the job more effectively OR at least play a CD of those beautiful "children of the night... what music they make."
I wish my best friend from college still lived up here. She loved wolves...for good reason. If her last name was translated in to English, it would be "wolf".
If the park was closer I'd try it myself. However, I don't think I'd fare too well with making a 4-5 hour drive home after a night of howling with the wolves
I would be on it like white on rice if I lived in the area. I used to listen to that album, "The Language and Music of the Wolves" over and over as a kid, and my boys and I often howl at the full moon. I also used to enjoy walking through my neighborhood howling so that all the neighborhood dogs would join in.
