Cowboy Country-Northbound-August 5, 2013 Departure

Though we've traveled quite a bit, we've never done so with a group. I'm a single mom with two older boys (14 and 17), and they are concerned that there might not be any similarly-aged peers in the group. Is there any family on this trip with older teens/young adults? And...even if not, my boys are really good with little ones; promise! (And, I'm a long-time elementary school administrator, so I'm sure to annoy my boys by gravitating to any little ones!)
Looking forward to meeting everyone,
Pamela
