Top Secret ConTraption, in 2001, was the final incarnation of ConTraption. That was the year that Camarilla was formally invited to be part of the con. Camarilla is the White Wolf LARP group at Oakland University, Rochester, Michigan. We also had The Great LukeSki as our filk guest.
This Michigan con was generally run in the spring months. In its later years it travelled from hotel to hotel. Of the three annual Michigan conventions - ConFusion, ConTraption, and ConClave - Traption tended to be physically the smallest.
I attended Traption from 1990 until 2001. I usually worked the con as well. - AnneZanoni. 2001 ConCom, Top Secret ConTraption
