[AT] OT - back filling fence posts

[Mike]

Hi All, we are replacing the 3 board fence around our horse paddock. The 
original cedar ones are failing after about 13 years. Our land is quite 
wet, and is heavy clay. After digging the hole with a 3 point auger we 
are left with dripping wet sticky clay to use as back fill. I was 
thinking of getting some road gravel to use instead since it should pack 
tighter. Anyone have any experience with this? Any help is appreciated.

Thanks,
Mike M
