I took Celeste to Empire Mine State Historical Park this morning for an easy 4-mile hike. Then I tripped over a metal bar exiting the park and my knee is sad.
If you are ever in Grass Valley, stop by this park. There is 840-acres of hiking trails and a neat historical mining museum that you can pay $7 to check out. I didn't, but you can.
I like the Union Hill loop.
Celeste does too:

I love going on walks with Celeste. She is just so happy. Also, she is not a freak on leash, unlike her older (not wiser) sister.
