Lost black and yellow DeWalt cordless drill near Roundup, Eastern Montana.

I lost my black and yellow DeWalt cordless drill around the Roundup area in Eastern Montana. I was using it to fix up a patio and packed it up in my truck at the end of the day, but I must have forgotten to put it back in. I drove about fifteen miles before I realized it was missing and went back to look, but it wasn't where I last saw it. It means a lot to me, so I’m hoping someone sees it and can help me out.
