One handed trash bag holder

I wanted something to use as I pick up trash during my walks for exercise in the neighborhood. I bought a pickup arm thing that makes it easy to grab the trash by the side of the road but getting it, one handed, into the bag was not easy. I took the original design and resized it slightly so it was about 7" wide. This makes it pretty easy to get the usual cans and hamburger boxes (and other less savory stuff) into the bag.
