If you haven't seen a juvenile bald eagle, don't start looking now. It's not the majestic, full blown white-topped ornithological (yeah, I used that word, I have a vast lexicon) embodiment of the greatest country on Earth you're envisioning.
For the purposes of covering you and your little one's bean bags we've with a mature bald eagle. Enjoy the family photo ops your kids will probably cringe at when they're 30. P.S. Adult sized Ball Hammock® are equipped with a fly while the child size boxers are not.
