Good luck Don - as long as your son can make up the school work, those two weeks in CO will be golden. I still remember when my dad took me out of school for a 10-day trip to the Blues in OR when I was in 8th grade. We lived in OK then, and my dad's partner flew us up there in his private plane (and hunted with him too). Talk about cool!
On a related note, he's a senior in high school. Maybe I was just a slacker, but I more or less coasted that year as I'd already completed most of my graduation requirements by the time my junior year was completed. I was out by 2:30 or so each day for athletics...not much book work needed for that!!
