MLS Goals Of The Decade
You can vote online for the winner at mlsnet here. I think that there's a few that definitely don't belong (Paule, Dempsey, Ralston), but almost all of them are great. If I had to pick one, it would probably be Brian Maisonneuve. I don't even remember that one, but it was awesome.
And because I care about all of you SO MUCH, here is a link to download all the goals onto your computer (47 mb).
