Inauguration Day in the TC part 2

After President Obama’s speech the loudspeakers of the mosque erupted with the call to prayer. I stuck my head out the door because I thought I also heard firecrackers or something with a big boom. As the call to prayer was still wailing on, a big cluster of National Guardsmen walked down the sidewalk. Love it, hate it, the call to prayer is one of those things that makes the TC and parts of central Shaw unique.
I wonder what went though the minds of these visitors in uniform as they walked by the mosque.
