I went for a bike ride the other day.  Just 10 minutes with the baby at home with Daddy, and I felt so free and alive.  Legs and heart pumping and the breeze blowing on my skin.  I used to do fun rides of 15 miles on any given day, charity bike rides of up to 100 miles, and Ben and I went bicycle camping and hauled all of our gear to a state park.
This year I was on my bike 3 times.  Once at 7 and a half months pregnant--a horrible idea, once about 3 weeks after giving birth--an equally horrible idea, and then this ride.  The most glorious 10 minutes all week.  I can't recommend it enough.
What little escapes make you feel free?
