Park and Parks are not consistent

It is debated whether the caspian SEA is a sea or a lake. I don't think something should be put in a group if there isn't consensus on whether it fits the criteria of the group. Also, most people know it as a sea, as it is called the caspian sea. Perhaps instead you could use Chad, a famous lake in africa, or another one of the great lakes like Erie or Michigan. /nm

Clever. This was a fun grid. I have never heard it called Caspian Lake.
