I believe this was done because a lot of the ladies have commitments in the Fall and Winter. Some are college bowlers going back to school, some are coaches (college and high school) who have to get back to work, others work in the private sector when not bowling and the summer offers the best time for them to use their vacation time to bowl. I doubt you will ever see a full "tour" for the ladies again. It is hard enough to do so for the Men, much less the ladies whose tour had to fold sue to lack of sponsorship dollars in the past. I do think you will this "mini-tour", summer tour, or whatever you want to call it again next year. It might garner more TV coverage on CBS Sports network or ESPN as well, depending on how the ratings look for the events this year.

For whatever reason, a lot of the women's events are in the summer.  For my wife, it was a godsend since she is a teacher.  If the events were during the school year she would never be able to compete.
