"My son and I are at the park."
Translation:Mi hijo y yo estamos en el parque.
I have made more notes about "del" and "al" than anything else so far (Pearl League). Duo needs to teach us, because this does not compute...Duo marks answers incorrect when they have used the "incorrect" as an example earlier in the lesson. I have never felt like giving up, but after reading MUCHOS Y MUCHOS comments, I can only surmise that this is unlearnable??
