I really like how you emphasize the shower/potty aspect of bugging out. For many on this forum, the bugging out trip may stall in an urban morass-- long before it's feasible to dig a latrine/wash in a stream. Having a good potty/shower setup is critical to stave off many refugee diseases. And, if it really gets bad, that's what we will be, refugees.

I figure, if history is any indicator, most evacuation orders give one a small window of about 2-3 hours to get ahead of the mass hysteria. But I've never been in one. Does anyone else have a good time frame for getting out of dodge? For hurricanes, I'm assuming pack the night before?
