Narrative:
I was entering the left downwind for runway 21 and the DC9 came very close as he departed runway 18. I thought the DC9 had already turned out but he was still on the upwind leg. Controller should have called traffic. I should have been more vigilant looking for traffic. DC9 could have been more vigilant.
