Late summer and September is when Key Westers head for Europe and other fun spots. The town gets quiet and everyone is sick of the heat and mosquitoes, so it's a good time to "get out of Dodge". I won't be headed to Europe any time soon but thanks to wetcanvas.com I can be a vicarious traveler. On wetcanvas.com there is a section where artists (very generously) share their photos and allow other artists to use them without any copyright infringement issues. I found a lovely little photo of Venice that was really fun to paint.
Note to artists; You might have to go through a lot of photos before you find one you like.
