Tar Pit & Mammoth
I was last at the La Brea Tar Pits on a field trip in second grade. I remember a few things such as this here pit with the sad reenactment. I also remember the pits being in the middle of LA.
But the thing that stuck out to me most was an African American woman at the register who had long finger nails that curled about 3 times.
I bought a toy Tyrannosaurus Rex from her.
