I assume, since you've posted here, that you got home OK. How late was it?
Nathan's time in the sprint was excellent!
We did. And thanks again for 1) putting this on, and 2) the offer to allow us to camp if needed. We got home at 2 AM and one of us was still awake at that point!
Yes, he has really started making great improvement in both navigation and running this past year. He's running XC in high school, which is great since he otherwise wouldn't have other kids to train with. Fortunately his school is not an athletics above all else school. I've talked with his coach and she's fine with letting him skip practice the day before US and NA champs so he'll gets a day off those weeks, realizing he'll still be running over those weekends.
