Here is one, it is a hard one to guess unless you have been there.Hint: there is a little tral and a big trail and it is in the Pacific Northwest.
I need a few hints... Is that I-90 down below there in that valley? It looks like you are facing east towards snoqualmie, which would put you north of I-90. Am I right?
Here are some more ( not for bikes but hiking).It is in N---- B----. I take it you grew up In Washington as well?
