Yep, that's it. Sadly, five or more affected rally-going families in the VA and NC/SC chapters are affected and three are dog owners. Ironically, one such family (the other 42' Cyclone) has one of the most involved dog "activists" I've ever met -- she would otherwise love the CG. But kids are in only 10-20% of rally rigs whereas at least 50% of rigs have dogs and usually it's more than 80%.
Picking a rally CG is hard. You don't get to pick just because you want to go there: it must meet the needs of the group. There will be folks who won't like it, due to distance, style, price, etc. This time an added kicker was the "adults only" rule. At least it isn't during the school year -- non-homeschool families might not have been able to come anyway -- and Cherokee is only a couple of weeks later.
