THEME: none, but four triples
GOOD ONES: Pitcher of milk? ELSIE [a cow used sell Borden products --- at least 70 years ago!]
Fall preceder TRIP
Letters from Greece ZETAS
Letters from Lancaster ZEDS
Chest protectors BIBS
Sign of possession APOSTROPHE [not requiring an exorcism]
BTW: With it HEP [actually the clue needs "once" otherwise it shows the opposite]
Pass a second time in a race
RELAP [I am familiar with LAP as a verb but RELAP is doubtful]
Festival d'___ de Quebec: annual music event ETE [Finally an acceptable clue for this Xword staple! Of course, I never heard of it but I'm so glad it exists and Barry cared enough to find it.]
I prefer themes, but this one was both clever and challenging.
RATING:

Three grins = Loved it; Two grins = Enjoyed it; One grin = A bit bland for my taste; One teardrop = Not much fun
