On a good day I could take the M2, a toll road ($4.40 each way!) but with no traffic lights. The run took 90 minutes normally, with the first, or last, 30 minutes being spent on Old Windsor Road. One afternoon I didi it in 60.
On a bad day the M2 becomes a parking lot, so I had to go via Victoria Road. If I was confident enough in my navigational skills, I could have avoided Vic Road but that would mean going along Pennet Hills Road ("DUN-DUN-dun!") to Hornsby, then down to Stives.
The markers show 30 minutes of travel on a good day. On the worst day it took me 2 1/2 HOURS to drive the 30km, 2 hours of that just to drive from Glenwood to the end of the M2.
I have got to get me a GPS.
The course was worth it. I have my Solidworksfu on and am ready to go when we get the new PC. First task is to update the assembly I am working on, then I have to start modelling the parts for designs.
