I did a practice run to Kinglake with my folks today. The roads were dead, but it's a freezing cold Monday...
Twisty turny but the cruise is only about 25 k's unless you wanna continue on to Healesville. MY suggestion since I am chief-pantswearer (or so I like to think) is to meet up at Kinglake Nat. Park and wait for the slowies in their non-dattos.
I'll tell you about it on the day, it's not hard to find. Right next to the "House of Bottles". Don't ask.
