Mendon, Illinois not Quincy Trump’s talking right now.
Mendon is part of the greater Quincy Illinois Micropolitan area so one can say it is in the area.
The rally is kind of between them, closer to Mendon, but Q-town is the larger town. If you were wanting to stay in the area overnight, I don't think Mendon has a hotel.
Just shows that Q is always nearby. :)
