I replied: "So, feel free to tell me this is a daft idea, but I've been wanting for years to drive the whole of Route 66 from Chicago to LA..."

Almost a year on, neither of us has seen sense, and so tomorrow morning we're off to Chicago!
We're staying in Chicago for the convention over the weekend, then taking a couple of weeks to drive the ~2,500 miles to Santa Monica (with a couple of detours to the Grand Canyon and Las Vegas), and then finishing off with another 400 miles or so up the Pacific Coast Highway to San Francisco to see the future site of Starfleet Headquarters.
Or perhaps our hire car will break down on the first day and leave us stranded in Illinois... Watch this space to find out!
