I agree with XYZ - for your own safety, leave them at the substation.

Thank you -- good idea. First I have to hear from them.

You can just post that they are at the substation and if any lost them to go there.

They could be ours - my husband walks up and down West Rock Avenue all the time and lost his keys a couple of weeks ago.

Please let me know if you're leaving them at the substation or if we can come take a look. We live on West Rock Avenue too. Thanks!

Please describe them and I'll let you know if they appear to be yours.
I may not answer until tomorrow morning (Wed.).

The keys were in a little brown zipper pouch with a black string (that was probably tucked into the pouch). I believe he had about 3-4 regular-sized keys in there.

Sorry, he just corrected me -- it's a black pouch, small, looks like a mini-backpack. He said there were about 6 keys. I hope that helps.

Yes, that sounds right. Please call me 203-645-8086.

Thanks, my husband Eric will be in touch!

Found the owner. Thanks to everyone for their thoughtful suggestions.
