"I was sitting in my office when I saw what looked to be very mangy cat, and then realized it was an opossum with 12 babies on it. I snapped a quick picture with my phone. I realized how slow she was moving and we have a 200 foot long building so I ran out of my office down to the other end of the warehouse, cracked open the exit door and lo and behold she was coming right for the door. So I pulled out the phone again and started filming as she made her way closer, and closer, and almost walked right in the door I was filming! Once I figured she wasn't coming in for a visit, I stuck my arm out and got the super close up at the end there."
