Orlin....Late August for the WI rally will be a problem for the members that attend the Western New York Mini Rally. It is usually held in middle to late August. I never miss the WNY Rally and really look forward to it every year because it is always a great time, so, the Rally in WI would not work for me.
Also, as mentioned in a previous comment, families with children may not be able to attend due to school starting in late August.
