Um...

I hate to say it but I seriously doubt that Fred Radtke is doing this. We know he's got boundary issues with regard to whose property (if anyone's) he has some sort of prerogative to make his mark on. But if he's ceased to even try making his distinction between "art" and "graffiti" I would be very surprised. I think this is either a "copycat" or more likely someone trying to make Radtke look bad (as if he needs any help).
