I can sympathise with the issue Les had and wish I could say that it was just an isolated incident.I visit parks mainly for my photographs and make a concerned effort not to do anything near other people or on the weekends-limiting myself primarily to weekdays when off.I have on occasion recieved nasty looks from people when I pull out a camera and children are in the area,so now I avoid the siuation whenever possible.Also I tend to wear fatigues and don't shave when I'm out and more often than not I now get friendly hello's-guess their either scared or think I'm in the military.
