Topes!
Topes are cyclist nightmare! Speed bumps, 'sleeping policeman', anything to force the drivers to obey 'stop' signs or speed limit. And since Mexican drivers are not too keen on obeying any sort of traffic rules, the creativity of officials as well as villagers (it's a common practice for a villagers to make their own topes) is endless in order to make a car to slow down.
That's a small collection we made on the way:
so-called 'vibradores', the worst ones for us
to pass this ones you have to get of the bike most of the time
a bit worn off
tire one
rope
small 'vibradores' spread over 50 m
a nice one
