"The legendary wooden gate The first established real estate Is lost in time like all the crimes that won this pleasant land" - Hudson

I believe the song Hudson is a criticism of the American myth.  The American myth is the notion that our forefathers heroically claimed our land and instilled freedom in all when in reality we forcefully and brutally stole this land from the Native Americans.  It's similar to the beautiful image of Hudson bay when the history behind it was so violent and awful.  >>FMI see: http://www.livescience.com/5530-mutiny-murder-happened-henry-hudson.html, basically the river was named after Henry Hudson because he was mutilated by his crew there<< This line particularly supports that point.

The first established colony was Jamestown and it famously was surrounded by a wooden gate  and he's saying that the few remember whatever the wrongs that occurred there were now.  The second part is more important and very direct (the crimes being the terribly dehumanizing treatment of Native Americans).  He uses the word pleasant ironically, demonstrating that our forefather's capturing of this land, the United States, was anything but pleasant.
