One of the murals in Flint Michigan
In the latter half of the 19th century, Flint became a lumber center, and at the turn of the 20th century the revenue and infrastructure from lumbering funded the establishment of the local carriage making industry. As horse-drawn carriages gave way to the automobiles, Flint became a major player in the nascent auto industry. (wikipedia)
Then again, I also like the "Soggy Bottom" sign!
