Being the Gray Man in and befor SHTF or WROL

The Grey man concept is quite simple: Even though survival minded and probably well trained when compared to the average person, carrying some gear which will likely include a handgun, the modern survivalist will not look like a freak of nature, like some sort of paramilitary lunatic or commando wannabe, but will instead get lost in the crowd because there's nothing peculiar in the way he dresses or behaves. This is something that at first glance shouldn't be hard to understand, but as always, when it comes to matters of balance between extremes, it can be tricky and what is reasonable for some may not be for others.
