Wild Foraging in a City

I live in a urban-ish environment- technically old mill-town territory. I do a lot of walking around town and wild foraging for things to add to my meals.
Does anyone else do this?
And, please no rude comments on "how not to forage, or wild harvest near the road", etc...

I wild harvest along country roads, because that is where we live. I know others would gasp at my dangerous behavior, harvesting within 50 feet of the roads. I often have wondered, how many 'organic' gardens in the cities are that far from any road traffic? So I consider the local conditions, and make decisions on each individual location.
