ok well i worked out the driving details but they can always be changed if you have a better idea or suggestiong total distance is to be about 180km so says my map and piece of string, start at Dural say the Macca's there as a meeting place where we drive along the Old Northern Road to Wisemans ferry where we can have a pit stop, get drinks and top up the tank for those like me who's car uses a sh!t load of fuel. then continue over the ferry onto Wisemans Ferry Road where we follow that then go left into George Downs Drive then right onto Springs Road which goes onto Greta RD/Bumble Hill RD then right onto Yarramalong Road, then right onto Old Maitland Road/Cobbs Road which brings us into tuggerah where we go right onto the Pacific Highway where perhaps we make a stop over at West Gosford Macca's for lunch or something (depending on what time of day) then follow the Pacific Highway all the way back to berowra where the fun twisty stuff ends and perhaps pull over on the single dirrection road going from Cowan to Berowra to say good bye or whatever.
Now how does all that sound to you guys? any better idea's? there is one alternative and that is making it even longer by going from Tuggerah through to the Entrance and back around the coast to gosford then back onto the Pacific High way but i'm not making this decision by myself as its for all of us so let me know what you all think.
