Interesting it might help the reader to include some reference links to where you are getting certain information from. For instance you mention a trail back in 2005 but no mention of its name or showing where that data is coming from. It is hard when people see an article like this to know where it has come from. Even more so without any kind of reference link helping backup information give in it. It's hard to upvote on something like this as I have no clue if you wrote it or if its from somewhere else. A very fact heavy post really needs a good backing of where that information came from.
