I spotted a couple more on my vacation, but wasn't able to stop and photograph. I'll list, in case anyone else is in the area, and wants to do them.
1) I was on the train between Maribor and Celje in Slovenia on my way back from Vienna. It seemed about 5 miles east of Celje just North of the railroad tracks at a home improvement/garden type superstore.
2) A casino just east of Bled in Slovenia seemed to have maybe 10 of them surrounding the parking lot.
