From the original JNUG version (October 1991):

There are neither tours nor sightseeing busses to Si Ma Tai which is
located near Gubeikou, approximately three hours northeast of Beijing.
It is truly a place where no foreigner has gone before.  To get there,
you will have to hire a taxi for the entire day.

Si Ma Tai is a mountain that rises straight up, with the top third
of it being almost vertical.  Someone, who must have been out of his
mind, decided a few hundred years ago that the mountain by itself was
not steep enough to stop invading armies from the north and that a
Great Wall was to be built on top of it.

If you go to Si Ma Tai with the intention of walking up this section
of the Great Wall after a round of golf, be sure to bring a rope ladder 
with some kind of hook attached to it, as, unlike the restored sections
opened to tourism at Mutianyu and Badaling, the watchtowers do not have
doorways you can walk through.  The only way to get past a watchtower
and continue walking on the Wall is to use the rope ladder to climb
into the watchtower through the windows.  Was I disappointed when my
climb ended at the first watchtower.  From the top of Si Ma Tai, you
are supposed to be able to see the Great Wall "snaking" its way along
the adjacent and lower Jinshanling mountain tops for miles and miles
and miles.  I'll be better prepared next year.

For the JNSE version (10/31/92):

It is a year later, and regrettably, I've been too busy to take a trip
back to Si Ma Tai this Fall.  I still want more than ever to get to its
top where the "Tower For Observing Beijing" is.

Si Ma Tai is a difficult course, and the sloping greens demand the best
of lag putts.  Most of the changes for this version involve flattening
some of the hills.  Since this is a hilly course, and in order to avoid
ridiculous bounces and rolls, I've tried my best to smooth out the areas
where you're supposed to land the ball.  Hope you enjoy your round of
golf in China.
