Round one complete. Against all odds I did not get pulled for "addition screening"... even with all the stuff in my carry on. Also noteworthy, and despite all the gear and zip ties on the zippers, TSA did not want to go through my checked bag either. Not sure if I am lucky or I am counting my chickens before they hatch. One more leg of the journey to go and if my bag arrives on time I will be making my first shore dives tomorrow.
