graffitti in Vancouver again

due to the great response and help I've gotten since I posted the first set of pictures on myspace, I posted some more showing new stuff that has been added recently.
it appears a new gang has moved in, or is moving into a large area of east Vancouver. the area is larger than I first thougt and seems to be expanding.
So....
once again I ask you to take a look and let me know if you see anything familar, or special notice is the picture of the number written down the corner of a building. I think this means something

you can find them on myspace http://viewmorepics.myspace.com/index.cfm?fuseaction=user.viewPicture&friendID=320387335&albumId=1274062

thanks
