There is a beagle pen on East Lake Road just north of Charles Moran Road in Moran. Not too far from Rudyard.
I don't much about the place. It appears to be a beagle club's running grounds. This might be what you're looking for if you can find someone who is a member.
I found this listing on a web site:
Strait's of Mackinac Beagle Club
Neva Johnson, PO Box 130, Moran, MI 49760-0130

Eastern Upper Peninsula Beagle Club

One of these groups might know about the running pen in Moran.
