Carnival in Cologne or - Kölle Alaaf!

Coming back from Helsinki, I needed a few days to recover from the cold in Helsinki. But on last Thursday was the first day of the carnival. I had to go, no matter the cost;-)
So, I was there, 3 days of drinking Kölsch, singing (partly) along songs in Kölsch-German was great fun. I was dressed as a copilot of a cheap airline. Was funny. But again, when I was back, this time I had a serious cold for 4 days...
I think they should change the rule when carnival is celebrated. 40 days before easter sucks. I suggest 40 days after Easter;-)
