In preparing for our trips, we do several things.
Fist we purchased 10 strollers of various sizes, and invite over several small children from the neighborhood. The strollers are smacked into our ankles while we do warm up streching, thus building up our pain tolerance.
After warming up, we walk at a quick pace and have the small children dart out infront of us and suddenly stop. Thus allowing us to learn how to hurdle them, or do the teetering off balance sudden stoppee.
And
Secondly we also go to the mall 3 times a week and find the large groups that "side by side" walk at .25MPH. Using this moving road block we practice our "tactical break formation, weaving around slow person, regroup" moves.
I am trying to figure out something to help us stop the line jumper(s) (aka my friends are up there) crustations. Maybe the polish chicken dance, thus allowing up to practice throwing our arms and elbows up to enhance the line jumper(s) face with misplaced black and blue eye shadow.
