What's Wrong with these Rigs?

Over the years, as a participant, judge, or steward, I've seen a variety of mistakes that have caused people to fail out of a draft test.  The following are photos of what might be overlooked during harnessing.  Now, I haven't made all these mistakes, but I've made some.  The others were stories from other judges.  Sometimes when people get nervous, flustered, or frustrated, they tend to forget to check over the entire done before indicating to the judge that harnessing is complete.  Always double check!
