we learned a lot about German train travel in the week we spent there. A two on the outside means second class- a bit obvious- but there is a little sign beside each chair that indicates if the seat is reserved and from what location to what other. So we were thrown out of our seats twice!
One thing that surprises me with my photography is when I find an interesting subject and feel that I take so many photos and when I review in Lightroom I almost always have less than a dozen. Maybe I am being too considerate to my travelling companion (wife)
two of the first photos that I took in Heidelberg and thought it would be an architectural bonanza for my photography - but didn't really turn out to be , possibly because the roads are too narrow to get a good perspective .
