[Highland Park] GMC keys found

Anyone missing the keys to a GMC? Mom was walking today on Sheridan and saw them on the sidewalk near 1228 Sheridan. She didn't see a GMC in the area, so if you know someone who was recently there and is missing their car keys, they're over there. (We figured the owner likely wouldn't be on the mailing list, so left them there in case they retrace their steps.) Thanks, Charles
