There are differing schools of thought on rebar.
If you just pound it into the ground, it leaves nasty ends that someone could hurt themselves--badly--on.
Here are the typical ways people deal with this:
*put plastic bottles or stuffed animals over the rebar
*"candy cane" it before coming out to the playa
*make some other kind of end, again before coming to the burn.
*taping it to an upright (This is rebar you are using for a shade structure with supports perpendicular to the ground.)
