The sound of almost two dozen basketballs being dribbled at once is something like quiet thunder. That’s what was going on in Suffield Academy’s parking lot off Mountain Road near the end of July, when Basketball World’s summer day camp was in session. Four sturdy portable hoops were set up on the lot, and Coach Scott Wissel was training a batch of enthusiastic boys of various sizes – generally 8 to 12 years old. Other campers were elsewhere on campus, being trained by Coach Paul Wissel, Scott’s brother, and several athlete counselors. Scott and Paul are the co-directors of the camp.
