My club used to have all the usual notices at the entrance including the words Club, Private, Danger of..., Low Flying Aircraft - you all know what I mean. We rebranded the Club as a Centre to make it sound more inclusive, removed the inappropriate signage and replace it with Visitors Welcome, Information and Trial lessons available, Enquire at... etc. We added signs showing the way to the office and car park to keep people safe.
Even private clubs need new members from time to time!
