If you cross at a ghost town, getting into the USA is really, really easy
Whitetail, Montana is a small village located just south of the USA/Canada border. It’s also the name of a border checkpoint that has been decommissioned by both countries.
A ghost town border crossing, if you will.
According to Wikipedia, “the small checkpoint along Montana’s border with Canada, which served about three travelers every day, was set to receive $15 million for upgrades under President Barack Obama’s economic stimulus plan.”
