Random photo

Hello all,
Photos.
I am somewhat intrigued by the random picture in the home page, showing ferries waiting at a river crossing, to possible transport trains over a river. Where might this be, and it would be nice to give some indication of the names of the vessels in your random introduction, and whereabouts if needed.

Hi PD's & hullo Len.... a number of years ago all members had access to a link that allowed members to scroll  through the opening page images

I did raise this, however the link was eventully removed  ...............Derek

You can get to most of the random title photos just by pressing the refresh button (backwards green arrow).  On the way you will get lots of repetitions, and even after 200 presses there is a strong chance that one has remained elusive.  It used to be a straight classroom probability exercise.
There are now about 100 photos in the pool.
If you want one particular photo, pr(success) = 1/100 = 0.01
pr(failure) = 0.99
pr (100 consecutive failures) = 0.99^100 = 0.36, which is still fairly high.
pr (200 consecutive failures) = 0.13, which is still fairly high.
pr (300 consective failures) = 0.05, which is 1 in 20.


In this instance it is probably my photo of the Posadas (Argentina) to Encarnacion (Paraguay) crossing, taken in Jan.85.  Already, a bridge was under construction, and had replaced the ferries by my 1995 visit.

There is a quite a lot about these in various postings: searching on Posadas should get there, then you get the names, then you can search on the rest of the posts.

Thanks Rod, I had an idea it was in either Africa of South America, but nice to know, quite a impressive shot.
Regards Len Knight.

Searching on 'Roque saenz pena' should bring up the lot.  IIRC, that is Parana River.
