Yucatan Peninsula

We are on vacation on the Yucatan Peninsula of Mexico. We arrived in the city of Merida on the 16th, but photos will all be back blips because until now (Feb. 25) we have not been any place where the internet worked well or at all! 
This peninsula is totally flat. The only hill I have seen in 10 days is the overpass on the highway! Thus, there is not much reason to have curves in the roads!
