Good morning all.
Richard, there is as much evidence for a giant bird as there is for bigfoot and unicorns. Zero, none nada. No bones, no fur or feathers, no droppings and most of all, no dead or alive ones.
You may well have seen a large bird but perspective can mess with your mind. Like every photo of a 6 or 7 foot rattler, is is just the perspective. Drive west down Briton Rd from Bryant towards Eastern. Look to the north and you can see a couple of broadcast antennas. There is a smaller on closer to the road than the large of the two. With the trees you can't see the ground to know exactly where they are. The one antenna appears to change size and move because the brain sees it as further away because it is smaller. It really is smaller. It is a weird thing and anytime the sun is out and I drive down Briton I look for it.
You were just three so you were far from an trained observer. I know your brain thinks it was real but memory is not like a video recording. Memories can and do change.
That is not a 10 foot snake!
