Good job!!!
It's sad how people from Sofia look at Vitosha as "the nature", yet they being the ones hiking up there are polluting that nature without thinking about it.

I live on the other side of the mountain and every time i see tourists i can't help it but hate them. I know not everybody is a miserable hiker, but most are and should keep to the other side where people like you would clean up a few times a year.
