Where's Ollie?

I must ask over 100 times a day, "Where's Ollie? or What's Ollie doing?". A couple of weeks ago Zachary answered "he's out front running to the street". That's when we learned that Oliver could open the side gates! Barricades have been erected and the backyard is now an escape-free zone. Yesterday I asked myself the where's Ollie question and here's where I found him.
