Amen to that, Swing. Thick skin and large gonads!
With 5% having a problem with it, Buell and cruiser, you are on borrowed time. Most don't care, but there are some folks who really have an issue with someone detecting in front of their house on property they maintain. A tribal "he (or they) doesn't belong here" mentality. Regardless of legality, there are homeowners who can and will make a stink about you hunting those ROWS (right-of-way strips). And getting the local governing body to enact an ordinance is typically very easy for a resident to do.
If there are two of you detecting you are less likely to be aggressively challenged but more likely to have the police called on you. I speak from experience, I hit ROWS hard for multiple years.
Hopefully you don't mind a bit of unsolicited advice:
#1 - Answer the what are you doing question with the phrase "city owned". As in "metal detecting this city owned right of way strip". Many don't realize that this is city owned property...of course, that's assuming it is city owned property where you are detecting. City owned is the most common, but by no means universal.
#2 - If someone has an issue with you, smile and leave. Get off the block and out of eyesight. Don't argue about having a right to be there. Being smart trumps being right every time.
Funny thing is, I never had a man give me any bleep. It was always women. The only man who gave me pause was the guy who came out of his house with gun in hand. He didn't point it at me just asked what I was doing. I told him and he just said "Oh OK, I saw you duck down and thought you were messing with my car," then turned around and walked back inside. I got away from detecting ROWS in front of occupied houses in fairly short order and just went to vacant homes, businesses on the weekend, churches on Saturday, apartments without onsite managers, etc. The problem with doing them like this is you really aren't detecting much ground. Even though ROW strips have a decent percentage of keepers per square foot, there's usually very little ground in each one.
What I have since realized is that those little ROW strips work best for me as great little welcome mats. It's the easiest permission to get from a homeowner, and often leads to permission for the rest of the yard.
