Hunter's Encounter: Mysterious Howl-Roar in East Texas Coyote Hunt - Bigfoot?

Darren, a experienced hunter from Central Texas, shares his encounter while coyote hunting with his brother-in-law in East Texas. They heard unusual vocalizations that they couldn't identify, describing it as a howl that turned into a roar, similar to a lion's roar with a small huff at the end. The sound was estimated to be around 500 yards away and they could feel the vibration of the sound. They heard the same vocalization twice, with the second one being closer to their location. After the encounter, they tried to elicit a response with different calls but there was no response. They couldn't make sense of the noise and concluded that it was something special, possibly called in by the coyote locator.
