The slippy back for some has been a problem getting to the Highline,so…
After tunnel #4 was built I put steps in. Place tried to stay away from the tree. Next the 2nd loop for the Highline.
I will level it, build a retaining wall and 10’dia is min. thus NO big trains. I had 20’dia stuck on the brain, but this will work for many folks. This won’t let me edit my title. Mis-spelled,Bob,please
