Hey you're very welcome I forgot to thank you for your post, I was curious to hear how it turned out. While generally nothing happens, the thing is, you can never know what to expect anywhere yes, so it's good to be cautious and watch out and not put yourself into situations that can be dangerous. Sometimes it's hard to see that when it's happening though until after.
My friend said that she always goes jogging in that park an that nothing ever strange has happened to her(in Berlin) it didn't put me off the city at all I loved the place still... if you ever get a change defintely go there it's such a crazy city! However of course these types of things do tend to make a person more wary in general... thankfully for us these things don't happen often! If Ever! 🙂 and yes... bike fever! I guess some people are just really crazy about them! 😜
