I have been visiting Rob's site for well over a year and he regulary updates it with new articles and portfolios. I really enjoy his images and lighthearted humour, and his articles always make the point clear. Considering his mobile lifestyle he is not shy of answering emails and questions although you might have to wait depending on his location. His other pursuits are also worth a read like REAL (Retired Early And Loving it) and are on his homepage.
(Have you seen his mobile home? IT IS WORTH A LOOK !http://www.robgray.com/motorhomes/big_wort/index.htm) Top bloke in my book and quite inspirational!
