Impromptu English classes in SE Asia have always been a privilege and a joy in our travels.

Buffalo always have that "What are you looking at ?" demeanor . . .

That's the fuel for those big climbs !

It's a big (and expensive) job to set up and maintain a garbage collection system. Credit is due to those communities who tackle the job.
