It's not REALLY free flying...Harley is clipped and can't get far and Maple has a permanent wing injury and can't fly well or far at all. Harley (as he is building more endurance) always wears his harness for now...we are looking into having a friend make a proper jess for him when flying.
They really enjoy it though. And thanks for the comments everyone...can you tell they are the apple of my eye!!??!!
