Fishing a Man Made Rain Shower

In British Columbia, we're blessed with access to all rivers as long as we walk/wade below the high water mark.  This doesn't always allow you to traverse all rivers but works most of the time.  I've heard some say they like the private waters of other countries in the world because it keeps angler numbers low where you're fishing.  That's great if you have the financial wherewithal but not so much if you don't.  There are landowners that either don't know the law or don't believe people should be able to pass through along the edge of their property.  I guess this landowner in Montana can be counted among the types that don't want people walking anywhere near their property.
