Traffic is not an inssue, Rock Island is part of the Quad Cities but isn’t a big place. You do have to be a US citizen and provide certain documentation in advance to enter the island, all the information is on their website.
The John Deere Commons area in downtown Moline is worth visiting, and if it’s nice weather the riverfront is nice. The fall colors will be gone by then, but the views up and down the river bluffs this time of year are spectacular.
Hopefully it will be nice weather. I'm originally from Central Michigan and know that it can get cold up there MUCH earlier in the year than it ever does here in Texas. What are the normal temperatures in that area for the end of November?
Ate at a Chop House near the Commons as I recall. Must have been good as that was 10 years ago.
