I had three departing BUR one Sunday afternoon (in an RJ). We climbed for the first one which put us into #2 at which point we dove and turned to comply with the RA and hopefully avoid #1. Then another RA and climb for #3. We were too busy to switch to departure...he probably pooped himself by the time we got around to him.
As far as we could tell it was all legal, just a busy GA weekend in SOCAL.
