Ron,

I'll second the suggestion from Tim Little. Get a Real Big camera bag. There is nothing like screaming "Official Photographer" than a big camera bag and a big honking telephoto lens.

Then glue some Tartan fabric to the Bag. Voila!!!

When you want to take a picture people will actually get out of your way you look so important. Then fiddle with the shot framing, the exposure and light readings. Even if your actually only taking a snapshot with auto setttings.
