Narrative:

Training a student in holding procedures over a VOR. We were in the process of turning outbound on the 050 degree radial. The other aircraft must have been tracking to the VOR for navigation purposes, or watching ground traffic on the highway below. We were practicing collision avoidance and saw the other plane as the turn began. We do not know if the other plane saw us as it did not deviate.
