Hello and welcome to An Altitude Problem, fresh back from a mountain bike ride, hacking and coughing from the big, wonderful gulps of 19 degree air. It felt so good. I can breathe again. I can take as deep of breaths as I need to, stretching my lungs without having them feel as though they are going to burst. A lovely sunrise, and meadows bejeweled by frost, just enough snow on the ground for Andy to roll in, stream crossings covered by thin sheets of ice. It's good to be home. Just a few pictures from this morning, since I just finished posting from our trip.
