I went to the Czech Republic last summer and Prague was insane. I was seeing people shooting up left and right. It's a horrible feeling to see that. Very dark.
Years ago, I used to walk freely around Frankfurt and never had any worry about any part of town. Last year....I made my way back to the city, and walked down one street about two blocks off the train station. Heron sales left and right....shooters doing right in front of me....just on this one street and for two blocks. Cops nowhere in sight....probably watched twenty guys shooting up at 9AM on a weekday morning. Guys just laying around on the street after getting their high. It’s destroying legit business on the street.
Vienna is a must see city. Their mass transit will get you around to just about anyplace in the city and suburbs. We spent a Sunday afternoon in the park and it was great.The museums are fabulous.Food, wine and beer are great, and it won’t clean out your wallet.
