Anyone have any ideas

I think it is Duchesnea indica, also known as Potentilla indica, very invasive. It propagates itself by stolons, so try to take the whole roots out if you don't intend to use the chemical approach.
It's a bit confusing - the fruit and leaves strongly suggest Duchesnea indica, but that plant has yellow flowers, and I'm seeing white flowers in the picture. On close inspection, there seem to be at least two stems with thorns - if the white flowers are appearing on those, then you likely have another invader mixed in there, possibly a blackberry. If the white flowers go on to produce similar red fruits to that already present, the plant may actually be a wild strawberry (Fragaria virginiana).
Given that Duchesnea indica rarely ever grows above 6", I think it is completely safe to assume that is not it. Not to mention, I don't see a single leaf that would make me think it is D. indica. The only plant I see in this picture is Rubus spp. The white flower, the thorny stem, the intact sepals all are just screaming raspberry. Even the beautiful ripe raspberry is screaming raspberry. It's a raspberry. =]
