Looking for some suggestions here. I am wanting to explore more graffiti in different train yards / bandos / spots. I'm not a writer myself but an artist that has great appreciation for the form and artistry. I'd love any recommendations on places to check out.

I live on the east coast and usually just check out what presents itself as I travel around. Of course NYC, Boston, Philly, Chicago, LA come to mind yet I am sure there are some amazing spots that just aren't on my radar. If this is an inappropriate ask - please let me know as I am not looking to offend.
