I got a canned response from them 4 days after I sent my e-mail. They mentioned that I would be hearing from one of their correspondents within the next few weeks. I just informed them of a few operational problems that I noticed and also about the distinctive odor of cat pee that seemed to be in all the monorails we rode in. Other than the e-mail acknowledgement, I'm not too sure what else they would be writing me about.
