Those native, low-growing trailing blackberries (Rubus ursinus)have such a wonderful flavor! All that flavor must be concentrated, since it's in such a small berry, lol. How great that you take your son berry picking, too! Some kids really take to foraging. They can pick a lot of berries! ; )
I'll have to make a post about skunk cabbage. They definitely take more effort than berries or many greens. But they have a unique place in foraging. Prepare them wrong, though, and it feels like your throat is getting shredded with little pieces of fiberglass!
Yikes ... to the fiberglass. You will have to get that post up soon. It can't be more than a month to go. Maybe I will give it a shot. A fun project for us to do:)
