"Hey Rachel,
I just want you to know that you made our trip so spectacular!! I haven't stopped talking about your cooking! I wanted to drop you a note to let you know that Kristen and i have been home for a month now, and we still talk about Montana every day- to everyone. I cannot believe what a great time we had, and it is all because of you guys. You are such great people, and I feel blessed to have had the experience that we did. A lot of things could have gone very wrong...but they didn't. We were safe, and had one of the absolute best times of our life. We are already planning next year!!
I wanted to personally thank you for your hospitality. You made us feel very at home."
