likewise in IRan when I worked there way back when ...
you'd see the concrete ditches along the streets...
in one place you'd see water running from the houses,
right down the hill, you'd see someone doing #1 in it,
a little further down the hill someone was washing clothes,
and further still someone was washing fruit in it !!!!
I didn't eat fruit for 2 years
but it was the best vacation of my young life - Systems Programmer and computers didn't get installed for 16 months !!! so we travelled around in our landrovers and on our yz400 dirt bikes !
