It was still early, about 1:30, and a good driving day, so we decided to just head home. Good time for a border crossing, it wasn't busy at 3:30 or so. We were home a little after 7pm.
It feels like it was a really good trip, although we won't know until we look at our pictures (grin). We saw a lot of things we wanted to, plus some we never thought we'd see (like Rocky Mountain Natl park).
