IF you want a good overhead view, goto maps.simcoe.ca, click on advanced mapping and zoom into the location (north side of 15/16 side road, just west of line 14, just off of hwy 11). You'll see the shape of the track pretty clearly. These maps also allow you to measure distances - it measured at 0.464 miles taking a good line through the corners. :)
Don't use google maps, it's not as detailed.
