As it stands right now, I'm looking at two weeks. That really isn't long enough when you consider that there are a possible 32 lighthouses to visit between Chicago and the Apostle Trip. The Apostle Trip is 3 days long. Then a possible 16 lights on the way to the reunion. The reunion is 4 days long. And another 22 lights on our way back to Chicago.
That's a lot of lighthouses to visit!!! (70 in 7 days time)
Ofcourse I will have to eliminate some of them as accesses or time my not be available. But that's what I'm looking at for now (before planing).
