Believe it or not, the email did come directly from TSA. I didn't download the .pdf file because my only internet access for the time being is on my work machine and there has been some problem downloading or opening any .pdf files from it for a couple of weeks now. Otherwise, I wouldn't have bothered to email and wait the 2 weeks for a reply. I posted the question in the forum, but go no answer to it. I just wanted to know the regs and thought that it would be beneficial to post the reply for anyone else who might be looking for the answer without the bother of finding the TSA site and downloading. Sorry if it created any problem.
