Sorry for the short notice, but I know of two off-road events this weekend.
1) Sprint Enduro Race at Meridian OHV park...Saturday and Sunday in Meridian, MS.

2) Moral Welfare Recreation (MWR) sponsored ATV Trail Ride on the army base at Ft Rucker...Saturday near Dothan, AL.
I think that this is only the second ever trail ride, and I want to show some support for the effort. I do not know for sure what to expect at this ride, but it is open to the public. It may be all 4-wheelers and just me on the only motorcycle, but the pictures from the previous ride show 4 or 5 bikes and one 4-wheeler.
