Well, Spencer has been in Korea for almost two months and hasn't received any mail. Turns out we had the wrong address. :(
For those of you who have sent letters, thank you!! Please know he's not ignoring you... he just never received them.
Here is the right address (and is now corrected on the blog):
Elder Spencer John Edwards
Korea Seoul Mission
Gwanghwamun Po Box 210
Oh. And he would love mail. :)
