Got those tiny little 3in tail numbers on my bird...When I'm up close and personal with the Locals (LoL) I watch their responses. If anybody's got their hands on their hips (or the cellphones), I head-off perpendicular (can't see the tail #), preferably into the sun and in a real round-about direction to my home airstrip - fly off towards another airport! If they're waving, smiling, or pointing, I feel obliged to give 'em an airshow :-)
