Hey Andy,
Here is what I sent John....
Hi John,
I wanted to send you a note about the contest. It seems the contest has drifted away from its initial premise which is to showcase your welders and their ability to join metal. I was not meant to be an engineering showcase. I can not understand how an air powered "Go Cart" is more in line with welding abilities than a project that took 50 hours to bend and weld. Sorry, these are just my thoughts.
