Metal Trailer Ramp (Tucson)

Lost silver/gray metal ramp made out of mostly angle iron.
Roughly 4 feet long and a foot wide with 5 rungs covered in expanded metal.
Bounced off of my trailer November 11 around 2pm.
Just South of Houghton and I 10.
A witness saw it, but I could not find it after driving around the area several times.
Thanks.
David.
