(This was in our mailbox today. They've obviously been dropping invitations far and wide this time to get a decent size crowd.)
One of the local real estate agents, Martin Property, holds a couple of these BBQs each year. Always LOTS of superb food, plenty of alcohol and no obligations/hard-sell. No fine print on the invitation (other than how to sign up for email newsletters) and no need to RSVP - just rock up.
This one is from 5.30pm TOMORROW, 21 October 2011. (For the dummies: If you're reading this and the calendar on your computer says 21/10/11 - it's on TODAY! Derp.)
