I would love to go that weekend but have a wedding to attend. I have been looking to make a trip out there and it keeps not working out. I may be available Aug 5th or 12th, except that the Sturgis Rally is going on those weekends. Is it even worth trying during the rally? Anyone have experience with that?
To get to and from the trail heads, you would have to deal with traffic more that normal. If you find a camping spot, it will be expensive. Other than that, the wheelin on the trails is mostly unaffected. May see more ATV's and spectators.
I plan to watch the off-road racing at Buffalo Chip on Sat. that weekend.
