It seems far-fetched to me that Bigfoot or Sasquatch could remain undetected here in the San Angelo area. There just aren't that many trees or caves. Those are the two things most associated with the beast.
Yet, there have been some famous Bigfoot sightings in the San Angelo area. Many of the sightings happen at this time of the year.
Around the world, people have been seeing strange lights in the sky. Even before the Wright Brothers made their first historic flight, people in all cultures have experienced things flying around at night that no one can identify. San Angelo is certainly no exception.
