Well...I figured Labor Day might be tough. We're still in the early stages of planning though and now is the time to throw out some dates that work for folks.
I think I can work any of the first three weekends in September. I still vote for leaving on Wednesday morning and taking our time to do either the Cascade route (likely a one way trip for us noobs so we aren't in a hurry), or some combination of OBDR routes that we could make a casual 3-5 days out of.
If it turns out my wife can't (or doesn't want to) go, then I could likely do mid August as well, but I can't plan on that just yet.
