I kinda hope that they decide to spread where the babies are let loose at. If they did more beaches between their original home and the new one in Texas, I think that would allow greater survival in the long run.

humans are a funny bunch. there's a group trying to save them while another only cares for poking holes in the Earth not giving a dam what the consequences are if there's a screw up lol. We go from north to south when it comes to mentality.

I would have been 6 ten years ago so I would have been at my grandparents. Because it’s late in the day currently I know 10 years ago it was a Saturday and I was fast asleep in my grandparents old house that I could walk to without a map. I live on an island so that makes things easy. No matter where I was on the island I could find my way home or to my grandparents. I remember what my baby food tasted like from when I was a baby... I have really good memory but also a really good sense of direction.
Hey, I live an hour away from South Padre Island! The nesting is still continuing, and everytime the turtles lay eggs, they block off that part of the beach. When it's time for the baby turtles to go into the sea, everyone gathers around and cheers for them.

Rotsku (6 months ago)
Ten years ago, exactly ten years ago. Even the same time of the day. I was in my bedroom, after a "long" day of kindergarten, in my bed probably. I even remember where my bed was back then. 40 sentimeters away from my current bed position. Tho bed was differend. Probably "reading" something or drawing. Or playing. Or praying night prays with my mom. Did I pass?
