Been watching this for awhile and thinking about it. I thought I would throw in my 2 cents since I am bored at work today.
Hot Springs is open 7 days a week and Green Acres is pretty much open all the time (just fill out form and drop money in box). You can connect those two with some of the Kiamichi Trail if you wanted to do some trail/gravel between parks in lieu of all asphalt (That would take a little more coordination and planning). Flat Nasty has new owners and I believe are now open every day. Disney is open every day, and I believe Rush is open everyday.
For me, the wheeling and the hanging out afterward would be what I would be interested in and not whether or not my rig can make it 3-5 hours on pavement. So, wheel a day(or two) at a park, camp at that park that night so you can have some beers and BS around a fire and fix what needs fixing, next day trailer 3-5 hours and wheel that afternoon, camp, wheel.
One idea-
Sat SMORR - meet at 9am in parking lot ( for those that could travel the night before or that morning)
Wheel all day, camp that night.
Sun SMORR - wheel all day camp that night.(for those that travelled on Sat and didn't wheel on Sat you would still get in a day at SMORR with the group).
Mon- travel to Flat Nasty (2 hour drive), wheel all day, camp that night (not sure if Flat Nasty has enough for 2 days)
Tues - travel to Hot Springs (5 hour drive), wheel rest of day, camp that night.
Wed - wheel Hot Springs all day, camp that night
Thurs - Travel to Clayton (3 hour drive), wheel all day at Green Acres. Green Acres is a park like no other I have been to, you may only do one trail all day and you may have the best time of your life or the worst doing it. So based on the consensus at end of day you determine Fri itinerary. But at least you are now back to a weekend where other parks will be open on Fri.
Fri - wheel again at Green Acres or move on to RMR (less than an hour drive) and wheel.
Sat - drive to disney and wheel or disembark and head home.
Smorr to Disney somewhat of a circle. That is somewhat centered for all those in KS, MO, AR, OK. For me in Memphis, I would probably join at SMORR on Sat and end my trip in Hot Springs on Wed. However, my wife is a school teacher and school is in in Oct so not sure she would be able to get Mon-Wed off and she could balk me going on my own. So I may just end up wheeling SMORR during the weekend. Taking off the whole week is a commitment that I am not sure my wife is willing for me to make.
Sorry for jumping in on all your all conversation with a long post but figured I would throw it out there.
