We race up and down this freeway, thinking it has been here for ages! But a lot of it is fairly recent.
The Rock you are standing in front of (hopefully), commemorates a section of the freeway (that you have just driven) Euroa to Balmattum, and was officially opened on the AB/CD/EFGH
Although the plaque looks like the log, it is not.
To find the real log, go to S36 42.(B+E+E)(D/3)(C) E145 38.(E+H)(B-E+A)(G-D+E)
Back in that car and off you go!
