I love this map, if you place your cursor over a location, it will give you some info on the place. Also, there are tabs at the top of the page for you to add a discription of any place that you know. You can also zoom in and out to see more or less of the area you are looking at.
I will be in Miraflores from Aug. 15th to the 20th if anyone wants to get together for a beer.
