I have to write? Couldn't this wait until Diane gets back?
It's common advice about visiting Mexico. Don't drink the water. In our case, it's the water in our tanks we're concerned about. Our water tanks are integral with the hull of the boat. With the bottom and sides of the tank there is no worries - the hull is all the fiberglass. But the top of the tank is plywood covered with fiberglass. 25 year old fiberglass. Which is now starting to rot (we see little chunks of wood fiber in our taps). So our latest boat project is replacing the rotting tank tops. Good thing we have a carbon filter on one tap to filter out the chunky bits.
Getting new eyeglasses and finding some fiberglass cloth was today's big errands. The glasses were easy, and were going to be ready in about 6 hours. For somebody used to the rather slow pace of Canadian eyewear that was a pleasant change. The fiberglass cloth took 3 tries before we found someplace with the right stuff. But Maia and I did discover a place that sold 1 L smoothies that cooled us off after a lot of walking in the hot sun.
