I am building a 6' wooden fence in michigan.I went and bought 4x4x8 treated post.I was planning on digging 28" to 30" holes ,but majority of people i've talked to say that i have to go 4' cause of the frost line,or i risk having the fence get pushed up because of it.
So now i have a dilemma ,either taking a chance with what i am doing ,or returning 40 post to get longer ones.Has anyone build one with those specs and had success with it?
