The closest urban area to me is DFW (Dallas-Ft. Worth), and I have yet to travel to another big urban setting with a field kit.
Last year I bought this book: https://www.amazon.com/Pen-Ink-Drawing-Simple-Guide/dp/0997046538 on Amazon, and it really helped push me beyond my "limits".
Perhaps next I should check out The Art of Urban Sketching, since it looks like a great guide. But then again, I think nature-scapes are a lot of fun too!
Take care, thank you for the chat :)
Nice, try the Urban Sketching book, hopefully it will inspire you! good luck :)
