Just for the record, I took my Hummer offroad twice, but there was so much dust, I got scared.
The mud was even worse. Do you know what happens when you drive down a dirt road? I looked back, MAMA! MIA!!! look at all that dust!!! I just washed this baby. Slowing down does not help, it gets worse. Stopping is totally bad, the cloud of dust just engulfed my big black beautiful Hummer. I tried driving faster and faster to run away from the dust, but that was hopeless, how fast can you go on narrow winding dirt road and crossing streams? I tried to back out of that narrow mud road all the way to the top, I got tree branch scratches which will hunt me forever.
Joking aside. Legend has it there is a lake at the end of that road, I tried twice, never got to see the lake. Always came to one section where the dirt road just drops down, too steep to walk for sure, maybe a person can do it on all 4, likely ok for Hummer, but I chickened out both times. I knew I have no experience to make that judgement. Wise choice.
