one of my customers he seamed to be a senior member of the club told me you had to be sponsored by a current member was the only way to get in. I worked with a guy that was is pretty well invested into the club Andrew L. I called their and left a message for him he either didn't get it or wasn't interested so I just dropped it .
The rules were changed seveal years ago to allow for non sponsored applicants to apply using a background check. There is an extra fee associated with the background check.
I know Andrew, he can be hard to get in touch with due to his work schedule.
