Do expect the old-bill around, too. If they appear more than twice each calendar year, it's because they have marked you down as a medium/high risk to the nation's security.
I'd NOT contact the local planners.
Don't do circuits, don't invite all your mates to beat the place up and then land every other weekend, either! Avoid aeros in the overhead - it just gets too much attention from NIMBY and those of a jealous persuasion.
