Add a print in too, when you get around to do it!
Now I happen to have a bunch of prints of people, and I want to send them off to them. Some to relatives and friends from afar. Others are friends on my same town, but seems impossible to track them lately.
I have a central post office near my route and given some free time and my tendency to stroll; I will mail some.
