The other day a snow bird gave me a business card that had his personal information on it and no business. 
I thought this would be a good way to convey your contact information to those you want to have it. The email can be tuff to remember as we get older so having the information on a card would be great. The card had a image of his motor home as well. If I need to find this guy the card would be all I needed. Tim DeCapua is a guy that hands out business cards like mad. He would be a good guide to follow.
