The yard is done! 
Time for a party! Got my switch panel installed, wired all the tracks, and tested all the routes and switching.
One little glitch surfaced that I overlooked when laying track. The Ross #202 yard switches that I used I "thought" I ordered pre-wired, but in looking at my invoice, I got the plain bare switch. So, power was not carried through the switch. In truth, that was probably a good thing in retrospect, I got to decide how the crossover to the next track was powered. However, I conveniently forgot about power until I was testing and noticed that the power stopped as the switches! 
That little oversight was corrected and now all is well.
I embedded a little lighted push-button toggle panel into the yard to power each track individually. Given my track record with switches lately, I added connectors at the panel so I can remove it if necessary to replace a switch!
