My 6 son and 8 year old daughter participated in their first parkour class tonight and had a blast.  The instructor was very skilled and struck a nice balance between free play and focused skill building.   The class size was a bit larger than I would have liked, but the instructor made a point to work pull students aside and provide individual instruction and feedback on form/skill practice. We decided to purchase a 10 visit punch card and look forward to our next class.
