I’ve been visiting Mexico on my motorcycle for more than 10 years. During all that time I’ve ridden some very rugged, steep, and difficult roads. But this was the first time I’ve ever seen a road labeled for 4-while drive only. JT and I were headed over the mountains, on the old road out of Real de Catorce, when I spotted this sign. I thought to myself, “this road must be something special that it, amongst all the tough dirt roads in Mexico, it is labeled 4 wheel drive only”.
