Got to go with Foxcotte on this one.
You wouldn't believe what goes through the airspace in it's own little world and disregarding any outside influence. I blame the GPS myself as it's now too easy to leave home without the appropriate maps but with the little box in the nav bag.
I've run into folks who didn't know freqs, callsigns, map ref or anything but requested them on air while inbound to a strip. These were all so called "professional pilots".
