Batalla Naval de Vallecas / Epic water gun fight

Time to cool down with some epic water gun fight!
What to bring:

• Gun(s) (preferably water guns)
• Clothes that can get wet
• Possibly a towel
• EPIC FIGHTING SPIRIT

According to the internet (https://musicaypitanzas.com/2016/07/06/la-batalla-naval-de-vallecas-2016/):
El más cercano es Puente de Vallecas.
So let's meet at the Metro stop for Puente de Vallecas. There are probably several, but I'll be wearing my Spiderman towel over my shoulder so I should be recognizable.
