Lost Keys! Help! (oakland north / temescal)

I had just unlocked my bike near the corner of 41st and Piedmont, and I guess my key ring must have fallen out of my pocket as I rode away.
Simply silver O-ring with about half a dozen keys, including one small brass key, a bike lock key (black/silver), and a couple of normal-looking keys.
If you found it, please drop me a line.
I have dupes but would love the originals back.
Thank you.
