Every time I go visit my parents across town, I think this will happen. They still live in the home of my youth. Unfortunately it's plopped right in the middle of the "Southside" which has long been heavily populated with "cholos" "vatos" "esses (sp?)" and all sorts of testosterone filled "gang bangers." I just know I'm going to get hassled one of these days. I'm really not worried about it unless there's an exceptionally large group of them.

You did the right thing. Just ignore them and go about your business.
