Austin to Terlingua

[the Ferret]

Tourmaster and Cortech make some great magnetic tank bags and strap on tail bags, or you might consider a dry bag ($12 or $14 for the last one I bought) from Wally World and some rok straps to put across the back of your seat

I wouldn't think you'd need extra fuel but I'm not familiar with the area. make extra gas stops if you have to ie: don't pass up a gas station if you are the least bit worried about running out.

Our tires are not readily available. If you are not familiar with the procedure for fixing a flat on the road or have a plug kit and compressor. At least join the AMA or AAA to get some tow coverage to the nearest dealership.
