Stuffy ears, Osprey on mast, Tom goes for a dive


Hello from Boca Chica Navy Marina 3/27/14--- Windy, sunny 72 degrees.
Went back to the clinic today and left ear is not getting better. Doctor changed prescriptions, and I have another 10 day wait.  We have decided to stay here another month.... it is not warming up North of us and we have time. With that decision Tom is flying to San Antonio to pick up our car from Jennie and we can store it here for 25$ a month. We can come back down and get it when we arrive at Norfolk VA. 
I am still hoping that this ear thing will clear up and I can get my last dives in to be certified, however I will wait until I am sure my ears are good to go.

Tom decided to try out his equipment and change the zinc on the bottom of the boat.  For non boaters -
Any time you have two different metals that are physically or electrically connected and immersed in seawater, they become a battery. Some amount of current flows between the two metals. The electrons that make up that current are supplied by one of the metals giving up bits of itself--in the form of metal ions--to the seawater. This is called galvanic corrosion and, left unchecked, it quickly destroys underwater metals.
The most common casualty of galvanic corrosion is a bronze or aluminum propeller on a stainless steel shaft, but metal struts, rudders, rudder fittings, outboards, and stern drives are also at risk. The way we counteract galvanic corrosion is to add a third metal into the circuit, one that is quicker than the other two to give up its electrons. This piece of metal is called a sacrificial anode, and most often it is zinc. In fact, most boaters refer to sacrificial anodes simply as zincs.
Well that is all the news so far.... One of these days I will pictures of fishes in the water. 
Tom in the water.... I know he should not have his
mask on the top of his head

Tom entered the water from the boat ramp


I watched Tom's bubbles  while he was under water.

we have these little birds visit our dock, I was feeling sad that it was
struggling in the wind with one leg

sneaky bird, had another leg

we have an Osprey that uses the masts as a perch to get
a better view to find fish
