Bubble Up: I got to ride in one of the new busses around here- the kind that has air conditioning! It was by far the most enjoyable bus ride of my entire life. The seats were plastic, which means no strange parts sticking into your back, the door open and close with the push of a button, and there are two TVs in there. Quite upscale for this country!
Bubble Down: My trip on the air conditioned bus brought me to a place where I had to walk by a large pile of burning trash, and I now smell like it. Yuck.
