Lost Leather Binder

Hi everyone! This is a long shot, but I'm hoping there is someone able to locate my husband's leather binder on the on ramp to I-5 from the Harvard Avenue on ramp.

He's a planner, and this binder includes 25 years of family history, camping, hunting, all the checklists and events we've done.

He left it on the top of my car when we left the hotel and it must have flown off as I headed north in I-5.

The idea that it's just lying there by the side of the road guts us!

Maybe a trash collector found it in the bushes there?
