Heard from a Democrat friend of mine that the local Dems are planning to have a large turnout on November 4th on Woodward at 9 Mile in Ferndale (a hip and fashionable suburb north of Detroit, a rather Democrat-dominated area).
If Biden wins, it will apparently be billed as a victory celebration.
If Trump wins, they state it will be a "peaceful protest".
Either way, if you're a business on Woodward and 9 Mile, I'd suggest investing in some plywood, or other window coverings, and some fire extinguishers, stat.
It would also be a good idea to avoid the area.
