Lost: a ring of keys on a red shoelace near the Halifax Common

Lost: a ring of keys tied to a red shoelace. I dropped it on Thursday evening somewhere around the Halifax Common.

Carrying them loose in a jacket pocket was my mistake. I know that.

They open doors to a building that is not mine, so I would like them back fast. If you found them, a bench or a fence post nearby is the right place to leave them. I will check this board again on Sunday.
