I took all the kids (save Rachel) to the park today and the kids noticed that the bramble berries are starting to ripen. I...don't know what sort of berries they are...precisely...though I think they're more like blackberries than raspberries (because they don't leave behind the inside part when we pick them). In fact, I think they're probably dewberries (which are just...wild blackberries).
I'm not a very brave forager, but my children always want to know whether things are edible (I'm just glad they check before eating), so I identified the bush (the closest we got was some sort of bramble/raspberry) and then did some quick research to see if raspberries or blackberries have any poisonous look-alikes (they don't). Then I swallowed my fears and told the kids to go for it.
(They're also in the "no-mow, natural-grow" area of the park, so we know they're not spraying pesticides in the area).
Since I'm pretty sure these bushes are blackberries, I'm also pretty sure they were rather unripe, so I didn't think the kids would eat very many (they didn't). They found them to be rather sour (because they're not ripe).
"Think about it..." I said.
