Here are a couple of Postcrossings that I catergorized as summer fun because they both contain water.
Doesn't that look like fun?
This postcard comes to me from the Netherlands.
The sender writes: Hi JarieLyn, I live in a small village nearby the sea and some lakes. On a hot day like today, it is so nice to jump in the water after work. Love that :) Have a great day! Corien.
This postcard comes to me from Portugal.
The sender writes: Ola! Greetings from a very hot Lisben. (+ 31'c) Here you have the map of the south of Portugal-where you find the most beautigul beaches of the country. (and also lots and lots of tourists) I've never been in Las Vegas. My favorite cities are Chicago (I lived there) and Boston. All the best. Alice.
Beautiful water. I will dream of a house on a lake, and dive in before I wake.
