That area is a direct walk from the church. The rocky beach behind search areas 2 and 3.

Thanks PFinder.
The image above is upside down to a traditional map.
Search areas 2 and 3 are to the east of the church
Firstly,
I would comment that I rather think that the terrain to the rear of search area 3 and the church is very steep, but I am not sure. Perhap Shining could confirm?
As one walks left (which is actually east) the ground drops away and the slopes become less difficult .... but look at the rough terrain carrying a child !
So on the slope basis alone, I am inclined to reject the area near to the church and the Fortezela and only consider the unlikely rough area behind search area 2.
Secondly
look at the distances to walk by the round-about Rua D'Escola (Smiths ) route. It must be half as far again to the only area that could be clambered over [possibly but unlikely] by a man carrying a child. There are alleyways that would take a man in a much more hidden way down to this area. All the alleyways around there are very quiet and dark
Thirdly,
To reach either area behind either of [south of] the two search areas, Smithman would have had to pass by various bars and restaurants and the ATM machine. He would have had to walk right thru the middle of town. I dont think that Smithman would have done that.
If the man were going to that rocky foreshore, I think he would have taken the shortest and least overlooked route ..... and that would not have taken him by The Smiths. He wouldn't have gone thru town.
Also if you were right, he was short of time, therefore as distance = time, he would have taken the far shorter route
No way, imo, would he have gone the longer route.
Soz, PFinder.
With thanks to Shining in previous posts for outlining all the occupied places that he would have had to go past if he took the Smithman route to those eastern shores. Sorry, I cant remember them all, but they were numerous.
