The Ride for the Heroes in Aledo, TX, is April 17 this year.  I've done this ride in the past and enjoyed it, and it is usually my first pay ride of the year.  This will be the first official ride for our new XTO Energy cycling team.  Typically, there's not a lot of recumbent turnout, but maybe it will be different this time.
