I've managed to do a bit of reading while resting and so recommend two books from the Apple Press urban sketching series, Sketch Your World by James Hobbs and Archisketcher by Simone Ridyard. Great reading, some fabulous pictures & even more terrific ideas for anyone wishing to improve their sketching skills in the urban environment.

Happy urban sketching
& all best wishes for 2016!
