Yeah your'e right, the chainlink fence keeps you from getting out onto the grass to go up to the expressway, and that retaining wall is like 12' tall.

You access it off of Roselle Rd. and Nerge. At that intersection take Nerge west (it's actually Pratt Blvd.) and follow it down untill just before it makes a hard right (1/4 mile maybe). There are three or four trails leading in(only about 10-15ft. of the road) I was standing just inside the second to last trail when I took those pics.
