This does not answer the question posed in this post, but I just thought I would respond and help fill up this forum post.

I was not able to travel to the northern part of Michigan to see Bill, but I am waiting for Sept. for his return to Mi. I have already made plans to try and get to the stores he is going to be at near Detroit.
I WILL be get to Saginaw for his visit there. I want to get there because it is my home town and I hope I can get my father to the store to meet Bill. I have talked a lot about Harbour Lights with my father and we look for them when we are able to get together and visit different places. I want to take two or three of my lighthouses to have Bill sign them and I hope to buy some at the signing and get them signed also.
If I remember I will wear my collectors badge and maybe meet some other collectors from these forums there.

Jim.
