I thought I would do a couple of drawings of the scenery as I looked out my kitchen window at the infield of the track.

It is here where the track is at its lowest level in between both sides of the land.
As you head into the first turn everything levels out and is almost even with the ground as you head into the backstretch.
Cold Day 1
Partway along the backstretch the track becomes higher than the ground and by the time you are at the second turn the infield side it is about 8' (2.4m) higher and on the roadside there is a 40' (12.2m) drop.

On the driveway side it is about 6' (1.8m) and on the infield side it is less than 2' (.6m) before it levels out in front of the house.
Cold Day 2
Just past the sentimental light the track starts to once again be lower than the banks on either side heading into the fourth turn.
