I actually really started my career and getting signatures when I went Bel Air Presbyterian Church in Bel Air California I did. Not actually attend the service however when the service was finished President Ronald Reagan graciously exited the church and was kind enough to regularly sign signatures for the few people that were waiting on him. One of whom happened to be myself.
I met President Richard Nixon in Yorba Linda California where he was attending an event for his presidential Library which is located in Yorba Linda California.
I met President Clinton a number of times including at Michael Jordan's Celebrity Golf Tournament at The Ocean Club in the Bahamas.
I had the pleasure of meeting Gerald Ford on a number of occasions at the Bob Hope Chrysler Classic Palm Springs La Quinta California.
So I have certainly had my fair share of success with getting the signatures of American presidents and a number of other dignitaries as well.
