Dogs: That Description Could Also be Applied to the Israelis in CTG
perhaps there will be less this year because the IDF has mobilized the reserves for the Lebanon invasion and its aftermath (GO IDF!), but there used to be LOTS of young Israelis just out of the IDF who hung in a clique and had wild parties in an infamous apartment where they sway by the dozens. They did NOT mingle with the other foreigners but ran around as a group, often with VERY hot Colombianas in tow (it is widely rumored these chicas were provided unlimited free nosecandy in exchange for sex).
Been 20 years since my first (and last) visit to Costa Rica so I cannot personally compare the two.
As for the heat and humidity, I was there in February and was STUNNED how pleasant the climate was (the locals complained about the cold spell!). My friend was there last week and swears he will never go back (and he lives in South Florida so is accustomed to hell like heat & humidity). Be prepared for Africa hot climate in August dogs (hell California was almost Africa Hot 2 weeks ago!) The global warming sceptics are denying reality-time to move FAR North if you like moderate temps!)
