Herons and rules of he road

Good morning! Chet and I went for our morning walk down to the estuary at the dry riverbed that separates the 2 parts of Loreto. The main downtown area is across the river from where I am. At the estuary we watched many herons, egrets and pelicans. On the bank was a group of larger dark colored birds warming their wings in the morning sun. I couldn't see them well enough to know if they might have been buzzards. There are lot of buzzards in the desert and in parts of town. We watched sardine size fish darting about in the shallows near the road.

The main route across the riverbed is closed to traffic as a concrete road is being built there. It will be nice to have a nicer driving surface than bare dirt, gravel or sand. I am curious to know how they are building to withstand the Fall floods. It does have a lot of concrete and rebar.

Rules of the road.
Left blinkers and left turns. When driving down here, we were told not to use our left blinker to make a left turn. A left blinker on the Transpenisular Highway means that it is clear for the cars behind you to pass. If you use your left blinker for a left turn you might be T-boned. We used the blinkers a lot to let traffic get past our 4 vehicles (a 5th wheeler, a motorhome, my van and a pickup). We all had CB's and the lead vehicle could tell us when it was clear ahead to "blink them on by". Sometimes we had to wave them on as the blinker signals weren't understood or believed.
If you do want to make a left turn off the main highway, move to the center line and when clear ahead take command of the left lane and go off at an angle as the edges are usually rough and bumpy. In some of the larger towns, there are actually left turn pockets like we usually see. Another way to make a left turn off the highway is to take an access road to the right then turn left to be at right-angles to the highway and when clear go straight across all the lanes to the other side. This is the preferred method to get into Loreto from the North and also Nopolo a resort/golf complex 5 miles south of Loreto at Loreto Bay. Cd. Constitucion is a much larger city and has 6 lanes for traffic. The two on the left and right are one way each direction and the two lanes in the middle are two way. You do not make a left turn from these middle lanes. Again, you go to the outside lanes and go straight across the middle lanes to the other outside lanes or across them depending on where you want to be.
Flashing headlights. While driving you may see an oncoming car flashing headlights at you. This usually means to slow down and watch for some sort of hazard ahead. Hazards are often cattle, horses or goats beside or in the road. Sometimes, there has been an accident or there may be workers beside the road. So............you slow down when "flashed' and watch for whatever hazard there may be.
