i actually used it myself for a few years on the road and it worked like a champ!! the rail is about 2" above the floor. but an illustrator being involved in and during a fashion shoot, that’s not a common sight. for instance, a hospital creates a lot of throw-away items that should be stored till it is shifted away. despite the format used to give this course, which should not be used in any educational context and even more in a professional. as it is expected, the primary and higher valued symbols are game related. the fat lady will sing very soon.
