I've been to all of Jackpin's WWCs. I only missed the Friday evening's "Ice breaker" dinner of WWC2000 and its Saturday action as I had some business deals going on at the time. However, I drove to the venue (an hour and a half from my house) on Sunday and enjoyed the action there...it was not locked down!?!
What I noticed was, each time the number of fans got smaller and smaller. Then, Jackpin moved out of San Diego (to East Coast?). In 2002, Tweety's husband Tom organized the FFE (Female Fighting Expo) with a similar format in Pasadena. Some of the girls' hanging out of the venue in skimpy outfits drew the attention of Pasadena PD. A couple of cops came in and observed what was going on about 15 minutes...there was no prostitution, no nudity...they shut it down because the number of people over exceeded the capacity allowed for that hall by the fire department. This convention attracted the largest crowd I have ever seen at such an event. Over 200 tickets had already been sold prior to the event day and while the cops were checking around, there were still fans waiting in line to buy tickets at the door.
Jackpin came back to San Diego and organized WWC once again in 2008. Ticket cost $250. This event was so poorly attended that I heard he lost money. On Saturday (the busiest day) I counted around 40 spectators...I'm not even sure if all of them were paying fans...Jackpin had family, friends, and volunteers helping throughout the event.
Right after that event, he announced on his Yahoo group that he would organize another WWC within a couple of months if 300 people bought tickets. Then he went down to 200 tickets, then he did some opinion surveys such as; whether it should be held in Vegas or San Diego, on a cruise ship etc.
The reason why there aren't live events in the U.S. is the lack of interest by the FvsF fans...not due to some jealous or prudent idiots. Unless you are doing something illegal why would you worry about those jerks? If there is demand for something, there is always a market for it.
I wish the best of luck to those who are planning a female wrestling convention.
