It was last week (but then again it was lashing down!) and tends to be quieter as winter sets in. If it is in use then they are usually done by 8-8:30pm or thereabouts
Sorry to hear about the poor turnout for Rockifest - would love to have been there to lend some support but was out of town for the weekend. On a brighter note, the weather looks good for tomorrow (Tuesday) - polo, ne'est pas?
If you've got room/patience for a beginner then I'm in!
