I beg to differ on the "very few moas in ZAB." There are 19 moas physically in ZABs airspace, most of which are divided into at least 2 or more sub-moas. Anyway, Gladden/Bagdad moa/atcaa (gladbag or happy sack as we like to say) are regularly hot during weekdays. We admittedly get our fair share of knuckle-head pilots coming out of the Phoenix tracon/Luke AFB areas that think they're the only ones in the sky. It appears to me that both parties involved were at fault.
