Ride your bike to work day . . .

So today was to first of (I hope) a number of days that I just ride my bike to work and back.  It's about a 36 mile round trip and takes a bit more than two a half hours total.  But it is a good haul, with hills.  I get to "rest" while at work for a few hours and then ride home again.  Thus, a good workout for the day.  If I don't need to carry work in, there's no reason not to do it.  I hope that is how my summer works out.  So hopefully this will be a standard pattern at least once a week.
