The terrain rating is attributed to the approach to GZ, maybe more so than the actual climb - there are several tough ways to approach. Make your way yo the 'Entrance' waypoint, then head west until you get the the stream and circle around. This is probably the easiest path.
When I was out in the area exploring the new park, I found plenty of 'junk' that was left behind by farmers, floods and foes-to-mother-earth. I did a little clean-up and I gathered some of the things I found to make some nice geocaching set-ups.

Remember: 'Trade even' or 'trade up' to keep it fun for everyone, but if you see something you'd really like, go ahead and take it and pay the sport back later.
GOOD LUCK!
