Turns out I have about 28Gb of footage off the dashboard cam which turned into around 11.7Gb of single worthwhile AVI. Bring a 16Gb+ stick with you and I'll bring my laptop, next biggest stick I have is a 32Gb stick full of my work tools. I also have the photos I took at that trail - most are good, one or two excellent ones (I love sports mode on the EOS). 29 photos, 241Mb.
Looks more promising for Monday or Tuesday up the tops for snow, but the cold front heading east has picked up pace since 10am from 25knots to 30knots and it's still heading this way.
Bonus: the high over NSW is weakening and may become a low, which will suck cold air up into the state causing not only rain but snow at altitudes. It should be 48-72 hours away from now, but if the cold front keeps accelerating we'll wear it nicely on Sunday. I'll know more after the 10pm synoptic update (we get one every 6 hours, and it's posted within 2 hours on the BOM site).
