Found: a set of keys on a green lanyard near the library in Santa Fe

I'm Amelia. On Sunday morning I found a set of keys on a green lanyard near the library in Santa Fe. I don't want to leave it with someone who might not look for the owner, so I'm putting it here. To protect the owner, I'm not saying everything about it: describe it to me in an offer on this post, and I'll be able to tell whether it's yours. We'll swap contact details through HelpBLESS, and I'll hand it over somewhere public in daylight. If you know who might have lost it, please pass this on. Please don't put phone numbers in the comments. Use the offer button and we'll connect.
