Rainy season is on the way. While it may not be here in full force for another couple months, there are increasingly frequent 'misty' nights. Perhaps most telling is the cleaning of drainage ditches all over the city. Alongside most of the bigger streets (and plenty of smaller ones) are ditches a couple feet deep, maybe even up to a full meter and about two feet wide. They are covered by one foot by two feet pieces of concrete that are about four inches thick and are shaped like very bold 'I's where the vertical line is nearly as wide as the horizontal lines. Basically, there are sections missing out of their long sides that allow for both water to flow into the ditch and to give a place where they can be grabbed to lift them out. In theory, they rest on a lip such that the top of the blocks are flush with the surrounding road. Sometimes, the ditches are covered by metal grating, but that seems much less common.
Starting a few weeks ago, road crews have been pulling off the concrete blocks and cleaning out the ditches. Every 50 or so feet along the side of the road is a big pile of mostly dirt (lots of dust blows around in the dry season), along with some plant matter, and human-made refuse. Last week, road crews came along and started to pick up the dirt piles so they're mostly gone now. Just an observation about city works and what I expect to be an interesting (for me) rainy season.
