LongShot - lost my usb storage device in the Glasnevin/Poppintree area/park

[NeedingHelp]

This is a very long shot and I probably haven't a hope in hell of getting it back but in the past week I have lost my usb storage device and I am devastated. I think I lost it in the Glasnevin/Poppintree area/park whilst fumbling for keys. It has lots of photographs on it, mainly animals and other personal stuff. If anyone comes across it I would love to have it back. It's a small black and green device.

Thanks
