Shoot first, ask questions later. This works better with cameras than with firearms, or at least there are less legal complications. Sometimes you don't even need to ask questions...
Just think of it as going on an urban safari. There's plenty of big game and it can be just as unpredictable and dangerous as anything rich people hunt for sport.
Just look for a watering hole or place where they gather to feed and post up. If your camouflage is good you'll have them coming right to you in no time at all.
Occasionally they will even walk right into your shot.
Humans are curious critters, once they become accustomed to you they start ignoring you.
That's when you can shoot them in all their natural glory.
These photos are all from my safari at the Thunder Over Louisville air show earlier this year.
