Even if you get a bit or rain here and there, Europe is even prettier with rain and when wet, cobblestone streets and all...Just be careful though, cobblestone can get slippery when wet...

"In restless dreams I walked alone
Narrow streets of cobblestone
'Neath the halo of a street lamp
I turned my collar to the cold and damp"

(The Sound of Silence, Simon & Garfunkel)
