Riders arrived for staging to find the flag line already prepared by John.  No surprise there.  We briefed and prepared for standing the line in very humid and warm air. Even though we were shaded we cycled folks into the cool air of the church because the flag line was to manned for 1.5 hours. Just prior to standing the line we presented Mrs. Houston with the PGR plaque.  As we took down the flag line the clouds became very dark and resulted in flags getting a little wet. The briefing was very short as the rain began to fall much heavier. The RC left on his bike just as the bottom fell out! He doesn't live far but was sitting in every red light with no rain gear...he was already wet when he left. It rained so hard you could barely see. I know how a drowned rat feels.
