Off to Mazatlan

Started out on the final day from Hermosillo to Mazatlan it is about 1000K so it was to be a long day. After 10 minutes it got longer, the "propania" bus had a brake line leaking and we looked for help but being Saturday we couldn't find any, so filled the brake fluid to the top and travelled without incident until we got to Culiacan and the "propania" could not find any, so we made the decision to continue on. Our calculations indicated we should be able to make it. Right after Doug said "well it only 12 KM so we could walk from here if we have to" it quit. So not being familiar with propane after eventually getting our spare propane in we arrived at 12:30 AM.
