Field Notes
The day we went out to find this invasive species it was crisp and chilly. The wind was roaring and the sound of dry leaves crinkling under children's boot filled the air. The fragrance of early Autumn put a smile on everyone's face.
Supporting Evidence

We found small red oval shaped or circular, blueberry-sized berries.

We found stems that were typically green or brown, and arched. They are stiff, have curved thorns, which are located all around the stem.

We found that the the leaves are dense, commonly having 5 to 9 oval shaped leaves per branch. The tops are dark green, and fuzzy from the tiny hairs located on the leaf. The edges are jagged like a saw, and have pointed tips.

Comments

You've correctly identified multiflora rose, by its fruits. I do want to point out the following:
(1) many types of roses have pairs of recurved thorns.
(2) all roses have compound leaves, with toothed leaflets.
(3) many types of roses have slightly hairy leaves.

So ... what is it that makes me know this is a multiflora rose, and not one of the others? First, the fruits that you show are characteristic of multiflora rose. And second, in your photo of the thorns, I can see the base of two leaves. Just above the point where they connect to the stem, I can see the stipules. Stipules are found on all roses .... they are leaf-like or wing-like structures located at the base of the compound leaves. On multiflora roses, the stipules are very unique, because they are fringed. They look like little green hairs sticking out to either side.

I agree with LoisStack, I think you need a little more information classifying the type of rose it is. Also, I love your username (haha).

I'd love to see you put your photography skills to the test and take a fab photo of the stipules next time you're out. If you do, add your photo to the comments to we can see it!

Thanks for reporting this invasive species, thereginageorges!
