They say he is a natural.

Marge loves what she does.  She works tirelessly.  Two of her co-therapists are unable to "walk" right now.  Brenda, figuratively, she is fighting an infection.  And Mary, literally, she broke her leg.

Fortunately Nathan is happy to work with anyone who will let him ride.  

 It doesn't feel like an hour goes by.  Although his last session he stopped 10 minutes early.  He couldn't set up straight he was so tired.  I guess that happens when you trick ride!
