Staying in shape?

There was a lot of discussion prior to trip about hiking boots, and I scoffed and maintained that my running shoes would suffice... this morning's run included a trail overlooking Old Faithful, and initially, my run was invigorating - there was a buffalo on the hotel grounds, and I ran right past him! Unfortunately I was spending too much time gazing and not enough time concentrating on the rocks on the trail in front of me. Inevitably, I tripped, tumbled, and the self diagnosis is broken little toe. But the good news is I have nine other toes to carry me forward :) - Jerry
