Thank you guys!
Caleb, that mosaic is the
Gaudi Dragon. I didn't go crazy for it until I saw it in person, like all work of Gaudi it's truly amazing and photos do not give it justice.
Giorgios,
you're the only person so far who has noticed the line up of Park Guell and the Sagrada Familia in the same shot. Thanks!

Pat,
you're definitely right. Today I shot my 3000th photo with the new 50D (and still loving it), RAWs are ~20MB each. In Barcelona I took 706 photos and tomorrow morning I'm off to another trip to Central Sardinia. Another bright note: I sold my 70-200 L on ebay in Italy. What sucks is that the Euro dropped from 1,65 to 1,20 US Dollars, which might be good news to you but to me that means a loss of $150 on the sale of the lens. Oh well, can't win them all, right? Sold the lens for about $420 equivalent (after ebay/paypal very high fees and postage). Trying to sell the never-used 28-135 IS USM now.
