Hanging door hangers 30 miles away from your city

Hi everyone,i am thinking about hanging some high quality door hangers and maybe do some post cards.The thing is i am looking at doing this 30 miles away in a city where there are already a couple companies cleaning windows.There are actually 2 areas next to each other that combined has a population of about 50,000.I just wanted some feedback on whether you think i would be wasting my time or not.I live in another state and am right on the border.Someone may see my door hanger and see a completely different area code and think where is this number from.I have seen stranger things.Even though most people should know how far away i am some people do not put two and two together.Any thoughts would be appreciated.

Get a separate phone with that state’s area code for this campaign.
