Dead Cities: reading the signs
In case you needed further evidence as to why you need to visit the spooky Dead Cities in Syria alone and not in the company of a guide (see my Doing it alone at the Dead Cities post), it's because it could take you some time to read the signs at the site. And the task will require all your concentration. Or you could skip the signs and follow my earlier suggestion to just take in the atmosphere instead. Who needs guides when you have great signage like this?
