Sounds like we need to note this in our diary. My wife says she'll think about it, but odds on she's up for it, so I'll pencil it in. I already did a google map route for it in page 2 of this thread suitable for us. Anyone else wants to tag along as a group, that's fine by me - and we've plenty of time to sort it out!
I'm estimating the date for 2012 to be either 31st Aug & 1st Sep, or 7th & 8th Sep. I've pencilled both weekends in just in case, plus a couple of days on each side - 1940km will take us 2 days to get there and 2 to get home, so it's a 6-day event for us.
