I have been painting in some "iffy" parts of town lately. All by my own. Not the smartest thing since a painter is like a sitting duck waiting to be pounced on. In one particular corner pictured below , a woman took pains to explain that I shouldn't be standing in the same spot where they gunned her son down... I did linger a little longer but I had to finish the painting at home because every car became suspect after the news.
I also have painted in this some posh spots like Wattles Park in Hollywood. It was beautiful and quiet but people tend to look at you with more suspicion in the well-heeled hoods' until you actually start painting and you stop making strange gestures , pacing back and forth and hand-framing.
