These were pushing themselves off of the plant. Based on how they taste and smell, we've decided they are in fact blackberries.
Edit: local horticulturist confirms blackberry.
Awesome. They're part of my childhood too - I had a friend whose neighbour had a huge blackberry bush that crept through the fence into my friend's yard, right next to their pool.
We'd sit in the pool all day eating them right off of the bush.
