That would be perfect if it was 1946 :)
I went on Google maps and followed the CN from La Crosse WI to Wausau WI. A travel by rail of about half a day.
There are over 20 towns along that route. Some pretty good sized towns.
Granted, they would cut them in half, do a half hour speech at each and get off at Wausau a fly out.
So it takes him a full day. They cant stop him. Want to know why? Its interstate commerce lines controlled by the feds-his cabinet.
They can stop him from holding rallies indoors though.
So what? He maybe gets smaller crowds-which I doubt, because they will line those tracks for MILES to just get a look.
How many boaters would he see if he was on the river?
Let em try and stop that!
