Ro,
In spite of what has been said, it really is no more issue than anything else. If trucks are moving, you can move. If you are set up to be self contained, you don't need to worry about finding a campground (we don't).
If the weather (Sonny is gone) turns that you want to go south first. Go that way. Buy fuel at Alexis Rd and if FMCA, plan to over night at the free FHU in Cinci. Bite south and west from there. You should know Michigan's weather, if you don't like it, wait five minutes.
We live on the other side of the TWP. My sig doesn't say New Boston because nobody know where that is. I don't know how that they cannot know, it is just up the road from Waltz.
