Don,
my last NBAA convention was when i was in college also, it was down in the New Orleans 1990. I flew a piper Apache from florida that year and it was a great trip and fun event. I specifically remember touring a Convair 580 corporate plane with a good size library in it and many nice rooms which felt like you were in a fancy house but could fly.
Anyways don, if you ever get to oshkosh in the future, please look me up down in fond du lac (11 miles south) i would love to talk, drink, eat about Commanders and planes in general. I do get out to the Reno races every year also and could meet you out there as well! I love the air races.
