Fuzzy, 8 to 10 minutes? You must be an athlete to be able to carry it standing up for that long.
Tony, I have thought about that shoulder strap idea. It could work. I'll try that.
I am also considering using a barstool. I sit on a barstool while the Ostrich is beside me standing up. Besides, I always bring a barstool with me because it is also a prop called the Yogano Barstool levitation. Maybe, the Ostrich and I could levitate while flapping its wings. Hmmm, that could be a good idea!
Here is a video of how my barstool looks like: http://www.youtube.com/watch?v=VmdJ9QuUUlw
