Katie,
I'm sure Nate would rather be down here with the people he loved the most. He's probably belly aching and arguing up there saying that someone made a mistake and it wasn't time for him to leave us.
On a more serious note, I'm so glad that you are letting your feelings and emotions out. It will be the only way that you will be able to heal in the long run. I know that probably everything you do right now, specially jumping, does not feel complete. However, with time that feeling of emptiness will disappear. What will always remain with you is the memory of Nate.
I wanted to mention to you before that back in March (or April) when we last saw Nate in the Skydive Sobe Boogie he ranted and raved to my girlfriend about how happy he was of being with you. After Reading all the posts on this site I have no doubt that you guys had an incredible bond. Tracy and I knew one half of that "special bond" (Nate). Hopefully one of these days we will get the chance to meet that other half. If you ever decide to come down to Miami, please let us know as we would love to meet you.
We send you our love,
Ricardo and Tracy
