Escuela Nacional de Airsoft have sent in details of an event they are holding. So far as I can see the site is all in Spanish, what follows has been through the lovely Google translator:
Dear Comrade, you notice the new event: We plan to install sound 1800W distributed throughout the field and camouflaged three mixers, more than 3 km of wiring, smoke machines, fog.
We will have a tap beer (without alcohol) in the area of town, assignment in a sealed envelope will be opened only when they give the word, spies infiltrated in the four groups making up the consignment, military hierarchy, props brought directly from the army REAL and much, much more, find out everything in www.escuelanacionaldeairsoft.com
