At what point are you walking on the pebbles before you realize that your feet have disappeared? Most of the times I've walked on a beach of pebbles it's been because I had taken mushrooms. This would not be a good thing for me to experience in that situation. My brain wouldn't be able to put it together. I'd also be confused why I was wearing women's flats.
As much as the typical camo pattern is standard green, grey, black, this seems to work much better. Regular camo literally only works in one type of place. They need to give the army suits that look like giant trees, with branches and everything. Even in the desert you'd be so happy to see a tree that you wouldn't question that it was the enemy. I'm a genius.
