Steve,
A 30" deep ditch the 190' circumference of the trailer would have been a horrible experience. But I have considered ground rings where a trencher was available...
I was pulling up melon sized boulders just burying the #4 GEC at 6"...
Remember, just a shovel, a sledge, and oh yeah, I had a spud bar too.
To be completely painfully honest, I'd say I've had to bend about 90% of the rods I've installed... I've never cut a rod, though.
I've never installed anything but ground rods, mainly because of the lack of training for any other method.
However, I'll try to be more open minded...
