Yeah the flu sucks Adam - hope you and Krystle get over it quickly!
Yeah the HUGE problem with a cruise is that the organiser of the cruise takes FULL responsibility for EVERYTHING that takes place on the cruise. I know we are not a group of louts, but even if the cops pulled someone over or came to one of the meet spots they would want to speak to who is in charge, check for the appropriate cruise insurance (and yes SAU:SA club cruises have this), etc etc. Sadly it is not as simple as just organising a cruise. Plus if we do it on a weekend afternoon we WILL get a slow car(s) in front of us and you end up doing the most frustrating 60km/h cruise in an 80/100 zone you have ever done. Hence why SAU:SA does dawn cruises, or goes WAY off the beaten track (like our next one in a few weeks is to Victor Harbor and takes some cool roads way out the back of beyond to get to Victor by the long route.)
