Ho, ho, ho. Thanksgiving is over, Black Friday is here and the holiday season has begun in earnest. Which means it is time for the annual arrival of New York's migrant tree vendor population. But those guys never seem to be where you thought/want them. Which is where we come in. For the last few years you've helped us put together a map of all of the tree vendors in town, and we need your help again this year.

So, if you spot a tree vendor in the wild please email tips@gothamist.com the location of the vendor (borough, street and cross streets please!) with the subject "Christmas Tree Vendor Map 2011" and we'll get the map up and running in the next few days. Can't be bothered to e-mail? You can add locations to the comments too. But please, remember to include boroughs and cross streets!
