Now that we're talking about ground handling, another generic comment. Perhaps not very applicable to the PA28, but more to other types.
When handling the aircraft on their own and needing to turn the aircraft around sharply, or pushed backwards without the benefit of a towbar to keep the nose wheel straight, you sometimes see people walking to the back and somehow pushing the tail down. Thereby lifting the nosewheel off the ground, and then push against the elevator to get the aircraft into position.
BE VERY CAREFUL when doing this. There are several very sensitive bits at the tail which are not strong enough for this job. Unfortunately, which bits are sensitive and which bits are strong enough is different from one model to the next. If you're not sure how to do this, don't.
