Race course wise, if it's not roped off and nobody is around, AND you enter it from the start, not midway through, fine and dandy (just make sure you're skiing around the proper side of the gates so you don't look like a total tool!!)
Terrain park, again, fine if you're not cutting anyone off, and then stick to one side of the park and not criss cross from side to side to hit the side of a ramp
