Just in case you are interested, this is what I know about this event:

The event is held at the Quakertown Vet Clinic, they do both small and large animals there. They have several acres of property where the fair is held. It is on June 5th,
with a rain date of June 6th from 11 to 4. They generally have between 50 to 100 exhibitors

the address is:
2250 N. Old Bethlehem Pike, Quakertown, PA 18951

They have horse rescues, many dog breed rescues, One by One cat rescue will be there, petting zoo, food court, DJ announcer all day, shuttle vans to bring the people in, photography, dog demonstrations (agility and therapy dogs), pony rides, etc., etc.

I will be with the One by One booth, but only if it is Saturday the 5th (I can't go if it is Sunday the 6th.......)
