Feel free to send her mail or goodies (but you have to use a delivery service like UPS for deliveries - they won't let you drop stuff off there).
HINT: It is very easy to use www.dearelder.com . You can send a letter for free through that service by just typing in the letter on their website. They print it out and put it in the missionary's mailbox.
I'm sure she would appreciate hearing from you!
