I just completed and won the Baja 1000 which I owe a good portion of our success to sandbags. We were stuck in some pretty nasty silt beds when I saw a sandbag on the ground. It just clicked. I filled it up then placed it under the rear tire that we had jacked up. It worked as good as a rock. Needless to say I emptied it and took it with us. We used it a few more times in the multiple silt beds. Has anyone else used sandbages before? Just thought I would share my silt bed experience. I now will be adding a few sandbags in my FJ40 when I go wheeling.
