I think of the mail as having a 50/50 chance of getting to it's destination. I've sent 2 cards with pix enclosed to POP this year. The 1st never made it, the 2nd made it there in 2 weeks. I'd say, if you're trying to send something valuable don't, but if you want to send a card or something sentimental can't hurt to try. If you enclose pix, make sure you have the negatives or memory card so you can print more if they don't make it....
