The Steeplechase side of the GIHP trails are only being temporarily closed in order to do some "selective logging." I found a decent thread on the SORBA website that has a response from the COO of Conyers. The fences are only temporary police barricades, but you can definitely hear some heavy machinery hacking away through the woods.

No word on when they’ll be reopening, but I hope it’s soon.
