Todd, your mystery missile appears to be the upper stage from a Nike-Ajax surface-to-air missile.

wasn't there a nike missle site in newport mi.?

There were missile sites all over the Detroit area. 

This link has a bunch of stuff on the Detroit-Cleveland Air Defense Area.

And Cap'n, anytime is good, just gimme a head's up before you invade again 

yeah. in Parma, Ohio (suburb south of Cleveland), there was a Nike site. it was turned into a park after decommissioning and called Nike Site.
