If you don't want to bother with mailing out traditional holiday or new year cards, and don't have the time to create your own electronic versions, you can send your own free e-cards courtesy of the National Parks Conservation Association. Choose from ten national park images, including the one of Yosemite above. Enter your personal message and your recipients' e-mail addresses. Click send. The recipients get an e-mail, with a link to the card on ncpa.org (hint, send yourself some samples first).
NPCA is a non-profit dedicated to protecting and enhancing our national parks.
