One last thing on this before I forget. This is an elderly man. Very nice and very thoughtful but up in years. I say this because you should make sure you ask him to bring along a designated alternate with him. He can sign as your proxy but you can also have another one, I recommend doing that. He can bring his son or his wife to sign that day he takes you to the Hilton.
I was in Vegas and he picked me up at the hotel last year and took me all around signing up for contests. Very nice man. I was happy I split a week in the Barbary Coast contest so I could grease him pretty good. Definitely recommend him, these older people take things seriously rather than getting a buddy who may forget about it one week....
