In the pic in post 100 where you see the large American flag hanging, there is a square building directly to the right of the flag you will see an overhead highway sign.
After looking at some other pictures including google live view I could see that there is a hill directly to the east side of 70.
If you look carefully at the pic in post 100 you can see a sliver of green grass in front of the courthouse, most likely meaning the entire crowd was on the east side of 70.
