Thanks John, I appreciate your reply. I have a confirmation number that showed up on my computer screen, that I happened to print, but there was no way for me to print it via the recreation.gov site. It was indicated that a confirmation email would be sent to me, but I didn't receive it. I ended up finding the phone number for recreation.gov, and spoke to someone there, who did see my reservation, but couldn't help me with the email confirmation since the Whitney Lottery is only on-line. She did give me a phone number that I can call tomorrow.
