We got to the house of their investigator and she wasn't home. So, we continue out even farther to the project housing to look and see if another person was there who would receive us. Then all of a sudden, someone threw a ping pong ball (at least that's what I thought it was) at us. I was really surprised when after a few seconds another one falls, followed by 3 more, followed by a downpour of buckeye sized hail.
Naturally we're freaking out (we didn't have an umbrella). We start running to the nearest door, clapping our hands (that's how you knock a door down here) begging for someone to open up the door to no avail. [Important Detail: all of the doors are flush with the side of the building and the only way to escape would be by someone inviting you in]
We ran from door to door for about 2 min. clapping our hands begging for someone to open up the gate to their patio. Finally a nice old lady opened her gate for us and we sat out the following 6 min or so waiting for the hail to stop (it was still raining really strongly). Once it stopped, we ran back to the church (about 12 min from where we were).
In this poorer area there isn't any good drainage on the roads, so on our way home so we were walking through 2 foot deep icy rivers the whole way. It was probably one of the funnest memories I think I've ever had here in Montevideo with the weather. Afterwards it looked from a distance like it had snowed, but upon further inspection you realize that it was just marble and buckeye sized balls of ice.
