Fluffy clouds over the canal locks

To be honest, this was yesterday, when I got a few good shots. Today I have been looking at a lot of blue skies over the Andes while scanning more slides. There are so many and they have got into a bit of a jumble, so just sorting them out into categories takes ages. I'm going to end up with some which might be impossible to identify. Ideally I should be doing this in the middle of winter, but to quote Magnus Magnuson: 'I've started, so I'll finish.'
