The place I worked for wasn't in a really terrible area.
Child welfare on the other hand...some places I'd bring extra shoelaces to tie around my pant legs to keep roaches and other creepy crawlies from getting up my leg. It amazes me the kind of awful conditions people can get used to. The smell in some places was so bad I started carrying a little container of Vicks that I could daub under my nose before I went inside. A lot of the time these folks couldn't smell it because they'd lived that way for so long.
