Thank you so much for all the suggestions everyone. I would say I'm probably a "belt and suspenders" type of person...but I'd love to hear more...any other suggestions, comments, stories???
Btw...42 days until I'm in SI!!!!! God I can't wait. I've been drawing palm trees and circling Central America on the map since I was a little kid. This is definitely an experience I've been waiting for for as long as I can remember
