Here is a wonderful video of the cubs at ABR.  In Act 1 we see the cubs cleverly managing to get around the sheathing on a tree so that they can climb up high and practice some acrobatic moves.  Act 2 shows us the cubs romping and playing while no one is watching and in Act 3 we see what happens when a cub is startled by a sudden clap of thunder.  It is so interesting to see the little bears and their behavior.  All of these activities are learning experiences for them.
