About Ron...
Originally from Shreveport, Louisiana, I lived in a Northern Mississippi suburb of the Memphis, Tennessee metropolitan area for several years before moving to Ohio. I am employed in Information Systems in the Cincinnati central business district (downtown.)

My favorite postcards are city skylines, or some unique sight that is native to your town or city. To my Finnish friends, I really like Kaj Stenvall cards if you have one.
Other favorites include the following:
Trains, planes, and automobiles
Bridges
Monuments and statues
City skylines and skyscrapers
Courthouses
Churches, Synagogues, Mosques
Skyscrapers
Ships, boats, and water sports
Sports cards
Political cards
People
Art
I would love to know your favorite word. Mine is "lagniappe" --- which means a little something extra. It is a Louisiana word of French, Spanish, and Creole origin.
Tourist cards are great.
