Well not to pollute this site with Jeep stuff but I thought you might want know what has been said about Powerline Trail (Hackberry Creek), here are some quotes from AzJVC:

This trail is truly a challenge for the moderate 4-wheeler. Some type of locking device is recommended, as well as clearance and 31' tires.

The trail is a solid 3.5+. There are numerous rock gardens that cannot be bypassed. Plenty of challenges to keep the heart rate up. Don't take a stock vehicle unless you want damage and breakage. The scenery is amazing!

I know 2 guys that ran this trail in late spring, I will see how bad they thought it was.

As for me, it looks like the wife and I will be doing Broken Arrow trail the weekend before so I doubt I will be able to make this one. I will keep my eyes open for your next run, I have always enjoyed wheeling with this bunch.
