OK, I'm going to add "Todd's Lighthouse", the Saginaw River Rear Range Lighthouse.

I'm not sure that it's eligible as it's owned by Dow Chemical but from what he's posted lately perhaps it is???

I sent him an email to ask last night but haven't heard back.

In the meantime maybe some other folks who haven't used up their quota think it's worthy of consideration and might like to nominate it also.
