I've made quite a few of their rides and flag lines, there are so many with flags already I never felt a need to mount a flag. Some of the PGR riders do these "Missions" as a part of their life, I dont know how they do it, once you have stood the line I think you'll agree. After the mission is complete, give yourself a few extra minutes, you will be filled with so many emotions it is hard to devote your mind to riding. The escorts are awesome, but so differant then standing the line. It seems I get mission info almost daily, often 2 and 3 at a time. Make sure you send a request to your area Captain, it's the only way you'll get mission info.
And a big thanks for joining up, time is our most precious commodity and to use it in such a selfless manner is indeed a comfort to the families of the fallen.
