I actually like poat apocalyptic art if its well researched and done tatefully, it allows me to analise possible scenarios and consider more options as to how I would need to adapt. There are some great images often very well thought out on forums like Deviant art and there is this article in todays Daily Mail.

For me as an individual being able to actually visualise the types of environment we could face within only 3 years of a societal collapse.
( A university took a stretch of B road that had been closed and replaced by a new road 100 yards away, they took time lapse photography eah week of the road and in places creeping grass and other flora completely covered the road surface in only 3 years) So imagine the extra burdon placed on you by missing manholes, drain covers, storm drain grates that are missing or removed ad a thin coat of grass covers it just waiting for your foot or front wheel to find it. One point I had completely missed but was filled in by studying PA art was falling debris. Yes I had picked up on the fact that many glazing panels are now secured only with some sort of flexible adhesive so they are more likely to fall if not fully maintained. But I completely missed roof slates and tiles lifted by frost or ice because no one had cleared the gutters and the water backed up in a capilary action style breaking free the tiles. This detail from a fictional picture is what prompted me to get a few caving / rock climbing hats and cycle helmets to protect my bonce of I have to go scavenging in a city.
Food for thought.
So just as post apocalyptic fiction novels can help you mentally prepare, I believe well thoght out PA art can equally help, just as seen in the TVs After Man.
