Go Karting is awesome fun - although the track here is quite small compared to what the Melbourne guys will be used to, but its still lots of fun, and the weather will be warm enough for them to have their outdoor section open :D Yep definitely a full tank of petrol, that way you've got plenty to get back to Melbourne. For us in Bendigo its roughly a 300km round trip, so its probably around the 400km mark for the Melbourne guys, or a bit more. There are about 16 confirmed and then a few +1s so I think the number is close to 20, though I reckon there will be a few who haven't posted that meet up with the others and drive up for it :)
