Maps are good...when you can find them. maps-of-mexico.com had the best information - much better than the Guia Roji we carried - but, as usual, not all roads were shown. The maps, along with a mix of compass-use, identifying landmarks that could be related to the maps, and gut feelings were used to lead the way. Being misplaced (lost) was never for too long of a time, but even though we had water, food, and shelter packed, the next source of fuel was somethimes a concern. Big Single, my riding partner and much more familiar with this area than I, carried the GPS - the one that didn't work when moving because the batteries rattled around like dice in a cup. Cool, we were going to make some sht up as we rode. We started this trip into Mexico from Del Rio, TX and our plans were loose. We had about a week to spend in Northern Coahuila, retracing a few past steps, bumping up to some old Rio Grande border crossing towns - all closed since 9/11 - visiting a hot spring along the Rio, and making our way SW to the Zona del Silencio. Other than some revived mine activity in places, motorized traffic could be counted on two feet - ten toes. We both wanted remote and that's mostly what we got. Why go - few services, an area active in drug smuggling and humans headed north across the US/MX border, and Zeta activity - I don't know, but we wanted to see what was and wasn't there.
