I'm in for all of those places. I am new to Melbourne (been here about 5 months, but have not ridden at all yet due to a new baby), so I am really interested in exploring. Sounds like we may be building a group of like minded riders.
January is usually pretty slow for me at work, so I am even open to doing a closer track like Dandy or Youies on mid week afternoon, say leave work around 3pm?
I'm going to call Apollo Bay tomorrow and make sure there are still slots available. Keep me posted on whether you are in or not.
