The national champion Bouncing Bulldogs jump roping team came to our area, and both Doodle and Tootle participated in a three-hour jump roping workshop. Tootle wants to lift her legs separately, so she doesn't quite have the hang of jump roping yet, but she did love doing double dutch. Doodle reports that she could do up to Level 7; I have no idea how many levels they are, but Doodle can do some pretty cool tricks.
The Bulldogs, based in North Carolina, certainly teach discipline. They don't allow talking in their practices, which means that the kids are silent for up to 90 minutes. They also don't let kids compete if they get a C in school.
