The value of hearsay, associated follow-ups and a vocalization report

Hearsay - something us researchers might cringe at. Other might find value with such information. How do we evaluate and determine such evidence or reports? As defined, hearsay means "unverified, unofficial information gained or acquired from another and not part of one's direct knowledge". How do we follow up? How do we deal with these situations? We also make a call to our guest "Josh" who believes he may have had a vocalization experience in the Huntsville area of Ontario. Be sure to join us!
