Richard and I were up at NAU this past weekend to visit Karen and almost got snowed in! On the drive down the mountain, it took all Richard's skill to just find the road sometimes--I was glad he was driving. But the drive reminded me of Kerry's comparison of being a lifelong learner to walking on hot gravel, which she often did as a child. The drive was definitely a challenge, definitely necessary, and the feeling of accomplishment at its successful completion was a shot in the arm!
