It was the best thing I did in Bolivia! Too bad more people don’t know about it... or maybe it’s a good thing!
I was at the same check point waiting for the bus to come...only I didn’t have a plate number. The police were freaked out that I was sitting there for hours. I didn’t speak Spanish either. The bus ended up coming 7 hours late due to a flat tire that happened before I got on. Luckily I have 3 other gringos that were on the bus who knew to look for me and I woke them up when I got on the bus to see if they were expecting another gringo. We arrived at our destination at 2:30 am and Ruban wasn’t there. Luckily, I was the only one with a phone and was able to call him otherwise we wouldn’t have known what to do. In the end Ruban was awesome and the trip was well worth it!
