In one of my lives I am a Quality Assurance consultant to both the Aviation and Mining exploration industries. One of the things I do is look for loop holes and then either exploit or block them depending on who is paying me. There is a national competition coming up and I have reviewed the rules (I will be a part of a team competing) and I have discovered enough "loop hole that you could drive 3 MAC trucks through side by side. Just my scene especially as how I was called on to advise the young bucks who wrote the rules and chose to ignore my "suggestions". Good fun
