In my research I have discovered that Montgomery County, Maryland, has its own official Coat of Arms, Flag, and Official Bird and Blossom. I do not recall Cache County having the likes.I did a--very--quick search and found that the Sheriff has a flag in Cache County. No coat of arms that I can tell. No flag. No bird. No blossom. I guess the county could have a contest? Maybe an Aggie would be represented?

(No...I don't live here. I live in Alexandria, VA. They also, as far as I can tell, do not have an official flag, coat of arms, bird, or blossom. They have a seal, but I am sure Logan does as well. So, Logan shouldn't feel bad. Alexandria is pretty great and very old, as far as US cities go.)
Official Bird and Blossom: robin and dogwood
