Default Sink posts how deep?

I need to install three 4x4 posts to support grape vines. There'll be some
sort of wire stretched horizontally between the posts, as done at
vineyards. However, I'd prefer NOT to pour cement. Reason: This project
could be a total failure if the deer decide grape vines=salad. They ate my
neighbor's car last week, so anything's possible. So, if I'm using 8 foot
posts, should 3 feet under the ground be sufficient?


What state do you live in? In southeast Michigan, we have to go 40" deep to
avoid frost heave.
