Here are some important tips to keep in mind when
sending mail to Rick:

If you are requesting an autograph, include a business-sized
SASE {Self-Addressed-Stamped-Envelope}
Do not go into your life history...Rick has other fan mail to read
besides yours! :-)
Be polite when asking for an autograph and/or information...you'll
stand a better chance of getting a reply from him.
By all means, do compliment him on his achievements...it will make
him feel great!
Last but not least, get directly to the point...tell Rick what it is that
you are seeking from him {autograph, photo, information, etc.}.
