Dzien dobre! 
I’m really sorry but I don’t speak Polish (ale umím dost dobře česky) - I’m from England originally but live in Prague and next weekend I’ll be heading to Warsaw for about two weeks (my my work, educational theatre tour) -
I hope to bring my 20" but it would be great to meet up with any Unicyclists in Warsaw. We should be staying in the centre.
Drop me a PM if you’d like to meet for a uni ride -
Cheers
Felix
