Trying to include too many activities may not work, especialy given our limited time. Off-roading is fun, but without radios or CBs it will be socially isolating. When I take a road trip, like to the Gorge, I like to detail my VX first, especially if I'm going to be meeting fellow VX'rs. After having done that, I'm not likely to drive around in a "dirt field", especially if I won't be airing down, using 4-Lo, and facing some challenging obstacles.
IMHO, this meet S/B a Show & Shine, then members who are interested can organize a real trail ride like Nachez Pass, Tilamook NF, Florence dunes...
Either way, I'll go along w/the majority. June 21 is out for me - it's Fathers Day and my HUGE extended family will be at my place.
