Here's one you may not have known: it is the 400 year anniversary of Henry Hudson's journey from Amsterdam to New York City.
As an Englishman hired by the Dutch East Indies Company, Hudson set sail in 1609 and the original purpose of the voyage was to find a passage to the pacific. Instead he found the area known today as the Hudson River Valley, as well as what would later become New Amsterdam... even later- New York City.
But this post is not just a history lesson, there's a big celebration in honor of his voyage going on throughout the year.
The joint effort between Amsterdam and New York City is entitled Henry Hudson 400. Among the big events, a special art exhibit of Van Gogh's work here at the Van Gogh museum, a self-guided multi-platform walking tour in Manhattan focusing on historical sites of New Amsterdam, a Water Forum at the Liberty Science Center in New Jersey including guests from both Amsterdam and New York, and much more. I mean... much, much more. I though I could list it all, but I can't, check the website for yourself. As each HH400 event comes up I'll be writing about it here on Trippist, and of course I'll participate in as much as I can.

So 400 years.. that's an impressive anniversary.
