It's funny how some of you say that it's not worth the risk to find a few pennies. How would you know what can be found if you have never detected in those areas?
I live in the murder capitol of Canada and spent most of my coin hunting days in the ghetto. These areas are some of the oldest in the city and are barely detected because most hunters are too scared. Worked for me! Never mind old coins, try hunting in the rich white-washed neighborhoods. You'd be lucky to find a penny. The "rougher" areas are loaded!
One of the best parks I've hunted was in the roughest part of town and that place was ripe with old coins! I'd detect for hours and when it got dark and the street lights came on, I'd even hunt till one in the morning by myself!
You guys are scared and live in a country where your allowed to carry protection. I'm not even allowed to carry a knife longer than 6 inches unless I'm wearing a turban! (Seeks are allowed to wear ceremonial daggers)
I'm not trying to be an A-hole and don't think any less of you. I completely understand the dynamics of the world today. Fear is how the masses are controlled and stay in line. That's why the media constantly spews fear. It helps corrupt governments, religions, and corporations to maintain their power over the people.
As for the ghetto, it is fear of the unknown. I've spent many a day there and have never been attacked or even threatened. In fact, I made some friends. All I ever had to carry for protection was common sense.
The only attacks I ever heard of on detectorist's were them getting jumped from a group of white kids who were bored to death from growing up in a rich suburb.

Humans and animals will attack if they sense fear. It's the law of nature.
But you are right. If you're full of fear, then stay away from those neighborhoods! I don't mind. More to be found!

Cheers,
Dave.
P.S. I don't have a problem with any of you but fear, yes I do. It has no place in my world and never caused anything but stress. NO FEAR!
