Those two tournaments are different because they are considered the WPBA's "majors". There is a different qualifying process for those. You qualify for the US Open by being ranked above a certain level or by winning a state championship. In a perfect WPBA world where we have more tournaments, it is mid-season. The Nationals, which has been changed to the Tour Championships is the end of the year thing based totally on rankings for the year. You have to finish the year out well to be invited. Winners of various other tournaments that are prestigous are also invited, ie, Junior Nationals, ACUI, APA championships (this has changed over the years, I'm not 100% sure that all of those get spots anymore). As you can see, they are not part of the Classic Tour because they have different qualifying requirements. They are in a way, reward tournaments for playing well throughout the year. As I said, that is based on a year more filled with tournaments.
I'm not saying that to argue the point. It is true that there is argument in not letting a man play in a womens event. The same argument came up with the PGA and the PBA when a woman was entered into a mens event. I believe a woman actually won a men's bowling event. I think it comes down to the fact that the women actually have an organization. I'm sure if there was a Men's Pro Tour again, it would be closed to women. Like someone else said, this is an independent event. In the long run, it could be a win/win for both sides if handled properly.
Just to clear up someone else's post about sponsors putting the girls in. I do thank my sponsor PoolDawg for putting me in. I appreciate the opportunity. I do have to say, that even if I didn't have a sponsor, I still would have paid the entry to play. I sponsored myself to play in the US Open 10ball as well. So it isn't based on sponsorship.
ForumGhost, your post was well written. I'm glad you are getting the chance to play in the Open this year as well! Good luck!
All in all, it is good to see so many players signed up already, 5 months before the tournament!
