Congrats mate, its gonna be one of the longest few days of ure life
RNPs great, although at times theres too many cyclists spoiling the fun. I'd recommend McCarr Creek Rd in Ku-ring-gai as well for a fun drive, bit narrow but quiet most of the time. Stay away from the old pacific highway up north - used to be a great drive but now they killed it with 60km/h limit and coppers everywhere
As for pics I did the northern beaches, but there are some nice industrial settings in ermington/rydalmere for night shots. If you're headin down the RNP you might as well extend ure trip to the sea cliff bridge and along the coastal rds - some very nice scenery and if you have a companion opportunities for very nice motion shots as well
and of course we demand pics ASAP
Edit: I see ure getting it from Parra as well - they're selling 370's like hot cakes over there. If you run into Mitch let him know Mark said hi : )
