OK, this whole thing is becoming a bit of a dog's breakfast!!!
I have tried to amend the list with starting location preferences (please amend if I somehow got your preference wrong!)
Percrime (Dave) - Whittlesea?
PennyR - Whittlesea to Flowerdale via Kinglake, return
gozzo - Whittlesea to Flowerdale via Kinglake, return -> can drive ute to Whittlesea (or Yea if ironbum!)
Oz - Ride from home to Whittlesea to meet the mob at the finish, then ride home again -> transport (bike) sorted
mash - you still interested?? what is your preference ???
Paul_f - seems to be keen on the Whittlesea/Kinglake idea, but happy with either
jimmy - "dragon lady" drop off in Yea, then pick up in Whittlesea -> transport sorted
Steve (Karen3.1 hubby) - Stay in Yea overnight; drive to end (Whittlesea), then ride to meet the mob -> transport sorted
Am I right in thinking that everyone, except for Jimmy, is keen on cycling from Whittlesea to Flowerdale (via Kinglake) and meeting up with the mob?
The route from Yea opens at 7 am apparently.
Campsite at Yea closes at 9 am, so most should be on the road by then.
Flowerdale rest stop closes at 11 am
Buses leave Whittlesea, bound Melbourne at 1:30 pm (however they will probably leave from midday onwards???)
So we'd probably want to get to Flowerdale at a reasonable time - maybe 9:30 - 10 am ???
<edit>There is a "first and last day" PDF
on the BV website now ... which has where the ride will be finishing from.<edit>
