Having waited for over an hour, I was about to leave and pick my boys up from Summer Football conditioning workouts. Then the action started, NS 221 called out a Clear Signal on track 1 at the Mile post 555 and just a few seconds afterwards, NS 212 called out a Clear Signal on track 2 in Cornelia, GA . Excited, I sprung into action and was able to shoot 212 here clearing the plant at Mount Airy, a few pics of the meet just behind me, and make it back across the tracks to my vehicle, all before NS 221 blocked me from doing so.
