Athens!
Many people who have been to Greece say that two days is all one needs to see the city. I've been here now three days and I have yet to see all the sights. I know I will have to return for a much longer visit to explore more cities beyond the capital as well as visit the famous Greeks islands.
It is really the heat I least like about my visit. I know it is summer time but the heat and humidity sure can take a toll on anyone's body should he not be careful. I have been wearing a Safari hat and putting on loads of sunscreen on my face, arms, and legs.
The sights have been pretty awesome. The view of the Acropolis atop a hill is jaw dropping especially at night when it is lit.
